Pneumatic Diaphragm Control Valve, 3/4-16 IN, DN50, PN25
Key Specifications / Features
Introducing our Pressure-Balanced, Cage-Guided Single-Seat Control Valves, available in sizes from 3/4 to 16 inches (DN20-DN400) and crafted from ASTM A216 WCB and WC6 materials. These valves, in Class 125-600 LB and DN50 PN25, feature high-performance sealing rings for superior efficiency. With a compact body and flow-directing vane, they minimize pressure drop, offer high flow capacity, and precise flow control. Conforming to the IEC 60534-2-1-2011 standard, they ensure stability, low noise, and minimal cavitation corrosion. Compatible with multi-spring diaphragm or cylinder actuators, they meet ANSI FCI 70-2-2013 standard for leakage.
