Pneumatic Diaphragm Globe Control Valve, WCB, LCB, DN50 PN25
Key Specifications / Features
Hits: 1
This versatile control valve comes in both straight-through and angle types, featuring high-performance sealing rings on the valve plug or cage. With a compact, flow-enhancing vane-equipped structure, it ensures minimal pressure drop, high flow capacity, and precise flow characteristics. Compliant with the IEC 60534-2-1-2011 standard, it guarantees excellent dynamic stability, low noise, and minimal cavitation corrosion, meeting ANSI FCI 70-2-2013 leakage standards. Compatible with multi-spring diaphragm or cylinder actuators, it offers compact design and high output force. Suitable for various high-temperature and high-pressure fluids, it can be customized as per specific requirements. Material options include ASTM A216 WCB, WC6, ASTM A352 LCB, ASTM A351 CF8, CF8M, CF3M, CF3. Sizes range from 3/4 Inch to 16 Inch, DN 20 to DN 400.
