Self-Operated Control Valve, Double-diaphragm, WCB, 1/2-4 IN
Key Specifications / Features
Hits: 1
This top-guided, balanced, straight-through valve is available in sizes DN15-DN100 (1/2-4 Inch) and class 150 LB - 600 LB, constructed from ASTM A216 WCB with flanged ends. The double-diaphragm micro pressure regulator includes a control valve, actuator, pilot, and pressure spring. It is designed to maintain a constant pressure of protective gas, typically nitrogen, at the top of a container to prevent the contents from contacting air, thereby avoiding volatilization and oxidation. This ensures container safety and is ideal for gas sealing protection systems in large storage tanks.
