Steam Jacketed Safety Valve, API 526, A351 CF8, DN50, PN16

Product Name: Steam Jacketed Balanced Bellows Safety Valve
Design Standard: API 526
Body Material: ASTM A351 CF8
Size: DN50, 2 Inch
Pressure: PN16, Class 150 LB
End Connection: RF Flanged

The Safety Valve is specifically designed for use in polyester, ethylene, urea, and other industrial processes. This safety valve is equipped with an Insulation Jacket and a steam purge joint to ensure safe and reliable operation of the system.
The discharge area of the safety valve is calculated based on the cylindrical or conical surface formed between the valve disc and the valve seat. This design makes it particularly suitable for applications with small discharge capacities, large back pressures, and stable system pressures. The Safety Valve provides a reliable solution for maintaining system safety and efficiency in demanding industrial environments.
