Indicates an imminently hazardous situation where disregarding the suggestions will result in death or serious injury. Indicates a situation where disregarding the suggestions could result in death or serious injury Indicates a situation where disregarding the suggestions could result in injury or property damage. When lifting the safety valve, do not get under it. In order to prevent an accident due to falling etc., lift the safety valve as vertically as possible. Never get under the valve being lifted. Check the weight of the safety valve and use a proper hoisting accessory for lifting the valve. Do not use the lever of cap or the safety valve for lifting it. Avoid using the lever, cap, etc. for lifting the safety valve. Doing so will affect the valve performance. It is recommended to wind a wire or nylon sling around the neck and bonnet or yoke at the outlet of the valve and lift the valve. Take care not to allow the safety valve to fall down. Many safety valves are of angle type and therefore is very unstable. When storing them, avoid piling them improperly. Doing so may cause them to fall down and get damaged. Store the safety valve indoors. When storing the safety valve before installation work, store it indoors. If it should be impossible to store the valve indoors, cover the whole valve with a waterproof sheet etc. to prevent it from being weathered. Install the safety valve vertically on the mounting nozzle stub. Install the safety valve vertically on the main body or mounting nozzle stub. If the safety valve is inclined, improper air sealing and unstable operation will be caused. The tolerance of safety valve inclination should be within ±1 degree from the vertical direction. Take care when tightening the flange bolts. When installing the safety valve, remove the dust cover at the inlet and outlet and check that no foreign matter remains. When installing the flange-type safety valve, take care not to allow the flange gasket from protruding and tighten the flange bolts alternately and evenly to prevent uneven tightening. Improper tightening will cause leakage. If the fluid is hot, there is a risk of burns due to leakage. The safety valve inlet nozzle stub should be above the valve inlet diameter. Inside the safety valve mounting nozzle stub, round the edge so that the fluid will flow smoothly from the boiler to the safety valve and make its inner diameter equivalent to or larger than the nominal diameter of the safety valve. The recommended R dimension of the inlet pipe inner diameter is 1/4 or more of the bore size. The pressure loss at the safety valve inlet should be within 2%. The pressure loss from the mounting portion to the safety valve should be 2% or less of the pressure setting of the safety valve. If this pressure loss is high, the safety valve may chatter during operation. When installing the safety valve on the elbow, the pipe diameter should be larger than the safety valve inlet diameter by one size. Use an elbow with a larger curvature (long elbow) and provide a support in consideration of the reactive force generated during the operation of the safety valve. Install the safety valve well away from the valves and joints. When installing the safety valve on the plumbing line, install it well away from the valves and joints that may disturb the fluid flow. It is necessary to install the safety valve at least about 10×D (D: Pipe diameter) away from them both upstream and downstream. Do not provide a branch pipe at the symmetrical position to the safety valve installation. When installing two or more safety valves on the same header/line, give due consideration to the installation spacing. When all the safety valves operate at the same time, partially biased pressure distribution will cause a malfunction. Pay attention to the reaction generated when the safety valve performs relieving. The diameter of the discharge pipe should be equal to or larger than the outlet diameter of the safety valve. The distance from the valve stem of the safety valve to the center of the discharge pipe should be less than four times the outlet diameter. The length of the discharge pipe should be as short as possible. Avoid bending the discharge pipe and lay it to the outside. The structure of the discharge pipe should be as simple and reliable as possible. The back pressure produced when the safety valve operates should not exceed 10% of the set pressure. If the back pressure exceeds 10% of the set pressure, unstable operation will be caused. The structure should be such that the safety valve will not be adversely affected due to thermal expansion etc. of the boiler, equipment and discharge pipe. When a drain pipe is connected to the discharge pipe, be sure to open its end. Do not constrain the safety valve with the drain piping. In order to drain the drainage generated while the safety valve is performing relieving and rain water, be sure to install drain piping. Provide the drain piping independently and separately from the other piping and take care not to allow the drain piping to constrain the safety valve. Open the lower end of the drain piping and do not install a cock or valve on it. Pay attention to the test pressure when a pressure proof test is conducted. Check the test pressure when a pressure proof test is conducted and never exceed this value. In the case of some safety valves, the water pressure plug is inserted into the nozzle for a pressure proof test. In this case, be sure to remove the water pressure plug before starting operation after the end of the pressure proof test. For further details, refer to the instruction manual. Do not move the lever of the safety valve indiscriminately. Other than when necessary, do not touch or raise the lever of the safety valve indiscriminately. Doing so will cause a malfunction. Do not use the safety valve as a foothold. Do not perform work while using the installed safety valve as a foothold. Doing so may damage the safety valve. If the safety valve should operate, a dangerous situation will occur. Pay attention to the installation environment of the safety valve. If the installation environment of the safety valve is near a heat source or exposed to cold air, a malfunction and improper air sealing may be caused due to uneven expansion and contraction as a result of external thermal effect. In such a case, change the installation location or take measures for heat-retention. When attaching heat reserving material, spread it to the lower end of the safety valve body drum section and do not cover the lock bolt for adjustment. Pay attention to the pressure when removing and disassembling the safety valve. When removing the safety valve for periodic maintenance etc. or disassemble the safety valve installed on the equipment, do so after confirming that there is no internal pressure in the equipment. Not doing so may lead to a serious accident. Secure a working space around the safety valve. In order to disassemble, inspect and adjust the safety valve, secure a working space around it. A space above the safety valve is also necessary for disassembling. Make consideration so that a chain block etc. for lifting can be hung.

To avoid this, the check valve is installed on the supply line to prevent reverse flow. When there is scale or dirt in the vessel, it is necessary to use the strainer to protect the pilot valve and make it operate normally. Manual lifting device Stop valve Manual lifting device Ejector By drawing the pressure in the main valve dome with the manual lifting device using the flow of the pressure source such as a nitrogen cylinder, the operating performance of the main valve can be checked even if there is no pressure on the primary side of the safety valve with pilot valve. N2 cylinder Field test connector & test kit Field test kit Test connector valve Check valve By using the field test kit, the popping pressure of the pilot valve can be checked with the safety valve installed on the equipment. Because it is not necessary to remove the safety valve from the equipment or to use a large device, a simple and effective test can be conducted.

The structure and material of SJ/SL series are designed so that the valve can withstand harsh high-temperature and high-pressure use environments. - 18 - Technology for enhancing product reliability (SJ/SL100-300) The safety valve should protect the pressure component from a risk of explosion by releasing the excessive pressure rapidly in the event of an emergency under harsh use conditions. On the other hand, under normal operating conditions, no fluid should leak from the pressure component and high sealing performance is required. The role of the safety valve is to perform these conflicting tasks. The safety valve should confront this challenge only with the force of the built-in spring. In order to perform these tasks, we adopt disc structures “Feather lip disc” and “Thermo lip disc”: the tip of the seat is machined precisely into a lip shape to make it flexible and proper operating characteristics and sealing performance are realized by making use of the temperature and pressure of fluid. In addition, our technologies based on long years of experience and achievements are incorporated into the parts such as the spring and spindle, thus creating reliable products. ■ York SJ/SL100-300 series adopts a yoke structure. By locating the spring in the yoke, efficient atmospheric cooling is performed. Therefore the vapor heat does not affect the spring during operation. ■ Spring We adopt a high-dimensional-accuracy cylindrically coil spring whose deflection exponent is made constant regardless of the pressure and whose load eccentricity is corrected. Alloy steel excellent in fatigue resistance, workability, hardenability, etc. is adopted as the spring material. ■ Operation adjustment mechanism The lower adjusting ring located at the top end of the nozzle is an adjustment mechanism for making fine adjustments to the pop-up operation in the early stage of relieving; the upper adjusting ring located at the lower portion of the guide is an adjustment mechanism for adjusting the blowdown. In addition, our back pressure adjustment mechanism adjusts the blowdown by controlling the back pressure produced behind the disc at the time of relieving of the safety valve with the back pressure adjustment needle or back pressure adjustment cock installed on the yoke. ■ Nozzle The structure of the nozzle of the safety valve is such that the integral full nozzle is screwed into the valve body and fixed and the lower portion is seal-welded. Highly stable carbon forged steel or low alloy forged steel is used as the material of the nozzle. The tip seat portion that is a contact surface with the disc is subjected to surface-hardening treatment by means of stellite filling.

The tip seat portion that is a contact surface with the disc is subjected to surface-hardening treatment by means of stellite filling. - 20 - Technology for enhancing product reliability (SL500−900) In addition to the relieving property and the air tightness of the seat surface, the safety valve needs a mechanism for providing high reliability. One example is the back pressure adjustment mechanism of our safety valve. Besides the clear pop and opening valve force adjustment mechanism, the unique back pressure adjustment mechanism is provided to adjust the blowdown of the safety valve. This mechanism is of yoke-type side needle system that features protection of the coil spring and easy adjustment work after installation. Also implemented is the cooling-type center throttle system in which the throttle opens and closes automatically according to the operation of the disc. ■ Spindle Because the spring thrust force should be transmitted vertically and properly to the center of the disc, the load resistant power and abrasion resistance property against the thrust force are required at the tip end of the spindle that transmits a spring thrust force of hundreds of kilograms to several tons. We therefore form into completely the same spherical surface the dorsal part of the disc and the tip end of the spindle that receive the spindle thrust force so as to ensure the centricity of the spring thrust force. In addition, we adopt a structure that transmits the load securely with a proper contact area. In addition to 13-chrom system stainless steel, chrom nickel silicone stainless steel that is more excellent in abrasion resistance property for high-temperature and high-pressure specifications is used as the material of the spindle. ■ Cooling spool and bonnet In the case of SL700 or higher, a cylindrical bonnet is used in order to protect the spring and enhance the vibration resistance. In addition, cooling spool is provided between the valve body and bonnet so as to prevent the spring from being exposed directly to high temperature vapor when the safety valve operates. This cooling spool portion also facilitates the adjusted back pressure exhaust of the center throttle, etc. ■ Valve body The drum section of the valve body is rigid and spherical. This structure is less susceptible to the reaction force of the blown-out vapor or the distortion attributable to vibration of the mounting-side and discharge-side piping. Because there is no useless blind corner in the valve body and the pressure distribution in the valve body is even, the flow toward the valve outlet is smooth. ■Disc For the disc structure, two systems “Feather lip disc” and “Thermo lip disc” where the contact surface with the nozzle is a lip face are selected and used depending on the temperature and pressure. The principle is as follows. The seat portion of the disc is formed into a lip shape. The lip end is deflected until the safety valve performs relieving. When the disc seat surface pressure decreases due to a pressure rise, the lip portion rises to reduce the contact area between the disc and nozzle, which keeps the seat surface pressure high to maintain the air sealing. “Thermo lip disc” is of build-up structure composed of a combination of a disc center and disc ring and is used for higher-pressure applications because its function is further enhanced as compared with the feather lip. The feature of this system is that the striker plates for preventing the lip portion from being deformed are provided on end face of the disc center and the back side of the lip. They prevent the lip portion from being deformed due to the impact given when the safety valve opens. This maintains the excellent air sealing function even in high-temperature and high-pressure areas and serves to enhance the durability of the disc. In addition, because there is a clearance between the disc and holder (flexible type), the disc will not be affected even if the valve stem is inclined due to external forces such as piping reactive forces.

FUKUI RE SERIES - 51 - Features Introduction FUKUI RE series safety valve has come out of FUKUI half-century-long accumulated technologies and experiences in designing and manufacturing of safety valves. Over the years, various types of FUKUI safety valves have been meeting the diversified needs of customers. We believe that, by adding this simpler, higher-performance and lower-cost RE series, we can help you prevent process lines from being pressurized. The applicable fluids are various gases such as air, steam, vapor and liquids. ■ Because the disc and disc holder are of assembly structure and the disc is discoid, the thermal effect due to high temperatures is minimized and excellent leakage preventing performance is delivered. ■ By forming the disc holder outer periphery into an umbrella shape and making use of the fluid reaction, lifting up is performed completely with an ultra pressure equal to or less than 110% of the popping pressure. In order to perform clear popping with the initial valve opening force at the time of valve operation and to adjust the blowdown pressure, the adjustment ring is provided on the upper edge of the nozzle. ■ This valve is composed of a necessary minimum number of parts and they are compatible with each other. Therefore the number of parts to be stored as spare parts is small and very easy maintenance with significantly less cost is realized. ■ The inlet and outlet face-to-face dimension conforms to API Standard 526. - 52 - Outline １． Standard installation method (a) The mounting flange is based on RAISED FACE FLANGE of the following standards. Class 150-2500 ASME B16.5 Standard Class 10K-30K JIS (b) The bolt holes in the flange is center symmetry. We will manufacture ring joint, male-female and tongue-groove flange surfaces to order. ２． Trim In the case of FUKUI safety valve, the trim refers to the nozzle and disc only. ３． Balance bellows type safety valve For sizes D to T, the balance bellows type can be selected except for nominal diameter of 3/4D1. 1) on the disc side and the other end is fixed on the valve body and bonnet side and the fluid passing section of the valve body is cut off from the bonnet section, the fluid will not leak to the bonnet section. Because the guide section of the disc holder is located in the bellows and is not exposed directly to the blown fluid, the important sliding portion is not damaged. In addition, the lift control prevents the bellows from being compressed excessively and damaged. Be sure to degas the bonnet (vent hole). If not degassed, the bonnet becomes a completely sealed chamber and cannot be balanced completely, which affects the operation and popping pressure. It is possible to know that the bellows is damaged by detecting gas leakage in degassing the bonnet. Type of bellows Spring constant of bellows kgf/mm Large Pressure resistance Classification Bellows material Application: The primary applications of the bellows type safety valve are as follows. 1-1 Place where the back pressure is accumulated or produced on the safety valve discharge pipe side (secondary side) and the back pressure fluctuates to affect the popping pressure of the safety valve 1-2 Place where the back pressure fluid should not leak outside when the popping pressure of the safety valve is adjusted 1-3 Place where it is necessary to prevent the parts (spindle, spring, etc.) in the bonnet from being corroded due to the fluid For the above-mentioned specification conditions, the balance bellows type safety valve or the bellows seal type safety valve is selected and used. The back pressure produced on the safety valve discharge pipe side is classified based on the property as follows. i） Superimposed back pressure Back pressure accumulated on the safety valve discharge pipe side (secondary side) before the safety valve performs relieving ii） Built-up Back Pressure Molded bellows Welded bellows small When the bellows can be molded When the bellows cannot be molded SUS316 SUS316L, etc Titanium, hastelloy, monel, etc. Small large 3) Bellows: The molded bellows and welded bellows are available. The classification is as follows. Vent hole Bellows Back pressure produced on the safety valve discharge pipe side (secondary side) due to the fluid flow after the safety valve performs relieving ２） Structure The structure of the bellows type safety valve is as shown in the figure to the right and its features are as follows. Because the effective area of the bellows is equal to the area of the nozzle opening of the safety valve to prevent the back pressure from being applied to the bellows-covered portion of the disc and balance the upper surface and lower surface of the disc completely, the popping pressure of the safety valve will not be affected even if the back pressure is applied and fluctuates. In addition, because one end of the bellows is fixed ４．Min. set pressure Model Conventional REC型 Balance bellows type （ＲＥＢ） Orifice Ｄ ～ Ｔ 15～ 120 Ｄ ～ Ｔ Min. set pressure MPa 0.035 0.175 - 53 - Model code ■ Model code system We specify the following model code system as shown below.
