HCP balanced cage-type single-seat control valve
I. Introduction:
The HCP balanced cage-guided single-seat control valve is an improved pressure-balanced control valve. It uses high-performance sealing rings on the plug or cage, which effectively improves the leakage class. The balanced cage-guided single-seat control valve has a compact valve body structure, with S-shaped flow passages, and is equipped with a diversion wing that improves the balanced flow of fluid around the cage, resulting in small pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow characteristics, and compliance with the IEC 534-2-1976 standard. The balanced cage-guided single-seat control valve has good dynamic stability, low noise, and small cavitation corrosion. When matched with a multi-spring diaphragm or pneumatic actuator, it has a compact structure and large output force. This product complies with the GB/T 4213-92 standard.
