API 526 Full Lift Safety Valve, A216 WCB, 2 Inch, CL 150 LB

Product Name: ASTM A216 WCB Spring Full Lift Safety Valve
Standard: API 526
Body Material: ASTM A216 WCB
Size: DN50, 2 Inch
Pressure: PN16, Class 150 LB
End Connection: RF Flanged

The Spring Full Lift Safety Valve is designed for systems where the discharge is relatively simple, and the pressure may range from atmospheric to a maximum of 10% of the set pressure. It is ideal for applications with small discharge capacities, large back pressures, and stable system pressures. The valve’s sealing surface is available in two designs: flat and conical surfaces. The discharge area is calculated based on the cylindrical or conical surface formed between the valve disc and valve seat. For systems with constant back pressure, the valve should be set at the differential pressure.
