Safety Valves

SF-Type Full Bore Safety Valve or Relief Valve

SF-Type Full Bore Safety Valve or Relief Valve

Fluid Gas, Air, Steam, Liquid
Pressure Range 0.05MPa~21.1MPa
Material Body SCPH2, SCPL, SCS13, SCS14, SCS16
Main Parts Stainless Steel, Hastelloy, Special Titan Steel
Bore Diameter 20A~200A
Note Safety valves or relief valves are widely used for various gases, air, steam and liquid.
The valve operates sensitively and can discharge the top quantity of fluid. The valves prevent various apparatuses in many industries from being fractured by excessive pressure. When the temperature of the fluid is over 400 ℃, the cooling spool can be built into the valve, resulting in the two-unit structure of the valve, the disc unit and the guide unit.

Note The valve is small and light. It operates securely at a low opening pressure such as 0.5Kg/cm2 or 0.05MPa. It doesn’t cause any extraordinary vibration or impact from opening to closing of the valve. The valve opens and closes the inlet according to variation of pressure. Set pressure is easily adjusted by the handle.
Performance (confirmed) For 150A X 200A pilot type safety valve
Set Pressure: 0.05MPa
Blow Down Pressure: 0.55MPa
Closing Pressure: 0.049MPa
Discharge Capacity (air) : 130Nm3/minute
