Self-Operated Control Valve, Double-diaphragm, WCB, 1/2-4 IN
Self-Operated Control Valve, Double-diaphragm, WCB, 1/2-4 IN
We are a leading control valve manufacturer in China, providing high-quality valves and control actuators designed to meet a wide range of industrial requirements.This top-guided, balanced, straight-through valve is designed for precise pressure regulation in gas sealing protection systems. Available in sizes DN15-DN100 (1/2-4 inches) with pressure ratings from Class 150 LB to 600 LB, it is constructed from durable ASTM A216 WCB and features flanged ends for secure installation.
Equipped with a double-diaphragm micro pressure regulator, this system integrates a control valve, actuator, pilot, and pressure spring to maintain a consistent protective gas pressure—typically nitrogen—at the top of a container. By preventing contact with air, it effectively minimizes volatilization and oxidation, ensuring container safety. Ideal for large storage tanks, this valve provides reliable and efficient gas sealing protection.Know more about China Manufacturer
