Spirax Sarco safety valves are widely used in food, beverage, petrochemical, steel, metallurgy, power plants and other fields, is the best choice for pressure vessels and piping equipment overpressure protection. Spirax Sarco safety valve design advanced, full range, and extensive material (bronze, ductile iron, carbon steel, alloy steel, stainless steel and other materials), widely used in the temperature range, all products are certified authority. To provide a safety valve in line with the requirements of the different standards. In the vacuum station system, in order to prevent the rated pressure relief valve downstream pressure is higher than the equipment operation, safety relief valve must be installed downstream of the solid. Set pressure relief valve must be within the maximum allowable operating pressure range of the device, between the normal operating pressure with sufficient pressure to prevent the valve off frequently lead to the sealing surface damage. Safety valve setting must be made by a credit lattice personnel. When valve selection should ensure the safety valve set pressure at maximum flow can be forced through the valve can Chao eggplant woman. SV615 safety valve: the whole trip, the whole nozzle valve. Suitable for steam, air can not afford the gas-phase chemistry of industrial application of non-hazardous liquids. For steam or hot water boilers, generators, pressure vessels, tank and air compressors, pressure relief valve downstream autoclave protection. Caliber DN15 ~ 50 pressure PN25 BSP or NPT threaded connections DN15 ~ 25 are available for health Closure connection. Sealing performance meets Api527 standards. Can provide soft seal spool. SV607 / SV604 safety valve: full stroke valve flange connection. Mainly used in steam boiler tubes. Pressure vessels, compressors and cylinders and other protective guard and most of the industrial process equipment. Accord DN3320TRD421 requirements, with TUV certification, caliber DN20 ~ DN150, SV607 pressure level for PN16 / 25, SV604 for PN40 / AN300, can raise the standard flange and aNSI standard DIN flanges. Sealing performance in line with A-P1527 standard. Spirax Sarco safety valve series
