Self-Operated Control Valve, Double-diaphragm, WCB, 1/2-4 IN

We are a leading control valve manufacturer in China, providing high-performance valves and control actuators engineered to meet a wide range of industrial applications.This top-guided, balanced, straight-through valve is available in sizes DN15 to DN100 (1/2 to 4 inches) and pressure ratings of Class 150 LB to 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 specifically designed to maintain a constant pressure of protective gas, usually nitrogen, at the top of a container. This prevents the contents from coming into contact with air, thereby reducing the risk of volatilization and oxidation. This feature ensures the safety of the container and is ideal for gas sealing protection systems in large storage tanks.
