Pilot-operated Control Valve, 1/2-12 Inch, Class 150-600 LB
Key Specifications / Features
hits: 0
The pilot-operated control valve consists of a control valve, actuator, and a pilot for pressure setting. It is ideal for controlling differential pressure in pipes carrying non-corrosive liquids, gases, and vapors. When the downstream pressure increases, the control valve closes. Trim features include a built-in bellows with a pressure-balanced structure for high sensitivity, a compact and reliable maintenance-free design, and a standard modular construction that allows for various combined controls through different assemblies. This self-operated, straight-through valve with a piston actuator is available in sizes DN15-DN300 (1/2-12 Inch), class 150-300 LB, and is constructed from WCB or CF8 materials with flanged ends.
