SF-Type Full Bore Safety Valve or Relief Valve

SF-Type Full Bore Safety Valve or Relief Valve

Fluid Gas, Air, Steam, Liquid
Pressure Rangee 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.
