Pneumatic Balanced Cage Control Valves, WCB, DN80, PN25
Key Specifications / Features
Hits: 0
Introducing our balanced cage single-seat control valve, available in both straight-through and angle types. These valves feature high-performance sealing rings on the valve plug or cage, ensuring minimal pressure drop, high flow capacity, wide adjustability, and precise flow characteristics. The compact valve body includes a flow-directing vane for enhanced fluid balance around the cage, conforming to the IEC 60534-2-1-2011 standard.
These valves provide 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, they are ideal for high-temperature, low-temperature, and high-pressure fluids, with customization available for special requirements.
