ASTM A351 CF8 Safety Valve, API 526, 2 Inch, 150 LB, Flanged

The ASTM A351 CF8 Safety Valve is a spring full lift type with a stainless steel body. It has a 2-inch (DN50) size, Class 150 LB, and PN16 pressure rating. Featuring flanged end connections and complying with API 526 standards, this valve ensures reliable pressure relief in industrial systems.

Product Name: ASTM A351 CF8 Safety Valve
Type: Spring Full Lift Safety Valve
Design Standard: API 526
Body Material: ASTM A351 CF8
Size: DN50, 2 Inch
Pressure: PN16, Class 150 LB
End Connection: Flanged

The Spring Full Lift Safety Valve is designed for systems with simple discharge conditions. It can handle discharge pressures that are atmospheric, constant, or may increase by up to 10% of the set pressure. In systems with constant back pressure, the valve should be set according to the differential pressure. The valve disc has two types of sealing surfaces: flat and conical. The discharge area is calculated based on the cylindrical or conical surface formed between the valve disc and the valve seat. This valve is ideal for applications with small discharge capacities, large back pressure, and stable system pressure.
