Diaphragm Pneumatic Control Valve, Cage-Guided, 6 IN, 150 LB

Pressure Balanced Cage Type Control Valves, designed for heavy-duty applications, boast a compact body with an S-shaped flow passage, minimizing pressure loss. Their stabilizer efficiently regulates turbulent flow, facilitating large flow capacity, rangeability, and precise flow characteristics. Featuring a pressure-balanced valve plug, they excel in controlling high differential pressures with minimal force. Integrated with straightforward mechanisms, the actuator employs a compact diaphragm actuator with multiple springs. These valves are versatile, catering to high/low temperature, high-pressure, or high-differential-pressure process lines, ensuring dynamic stability, low noise, and resistance to cavitation/flashing. Size Range spans from 3/4 Inch to 16 Inch, corresponding to DN20-DN400. Constructed with ASTM A216 WCB materials, they offer two valve actions: FO (Air to close) and FC (Air to open), each combined with respective direct or reverse action actuators.
