Diaphragm Actuator Control Valve, 1/2-12 Inch, ASTM A216 WCB

We are a leading control valves manufacturer in China, providing high-quality valves and control actuators customized to meet a wide range of industrial requirements.The pilot-operated pressure regulator (before-valve control) comprises a control valve, actuator, and a pilot for precise pressure setting. It is specifically designed to manage differential pressure in pipelines carrying non-corrosive liquids, gases, and vapors. As the upstream pressure increases, the control valve opens, ensuring optimal pressure regulation. This self-operated, straight-through regulator features a piston actuator and is available in sizes ranging from DN15-DN300 (1/2-12 Inch), with pressure ratings of PN16, PN40, and Class 150 LB, 300 LB. Ideal for reliable pressure control, it is widely used in various industrial applications.
