Overview
This kind of product is a pressure-balanced high-pressure cage regulating valve. The valve body flow channel is S streamline, with small pressure drop loss, large flow rate, wide adjustable range, control valve and multi-spring film actuator. Compact and powerful, the valve has good dynamic stability, low noise and small cavitation corrosion. It is suitable for high voltage drop occasions in the power station industry.
