Cage-type single-seat regulating valve, a high-performance single-seat regulating valve, is suitable for the occasions when high pressure difference is prone to flash vaporization and cavitation. The fluid channel was a streamlined S channel with low pressure drop loss, large flow, and wide adjustable range. The guiding area of the valve core is large with good vibration resistance capacity. Regulating valve is equipped with multi-spring diaphragm actuator with compact structure and large output force.

 Main performance：

Leakage level: meet the standard ANSI B16.104 Level IV, less than the hysteresis error, 0.01% of the rated Cv: 3% (without positioning device); 1% (with positioning device).
The adjustable range: 50:1
