Pressure Balanced Control valves, 3/4-16 Inch, ASTM A351 CF8
Key Specifications / Features
Hits: 0
The balanced cage single-seat control valve comes in both straight-through and angle types. These valves employ high-performance sealing rings on the valve plug or cage. The valve body is designed to be compact, with a flow-directing vane that enhances fluid balance around the cage. This results in minimal pressure drop, high flow capacity, wide adjustability, and precise flow characteristics. This design adheres to the IEC 60534-2-1-2011 standard.This control valve offers excellent dynamic stability, low noise, and minimal cavitation corrosion. It meets the leakage standard outlined in ANSI FCI 70-2-2013. The valve can be fitted with either a multi-spring diaphragm or a cylinder actuator, providing a compact structure and high output force.Suitable for handling various high-temperature and low-temperature high-pressure fluids, the sleeve control valve can be tailored to meet specific requirements.
