Product Details
SYV77
High pressure cage regulating valve
Linear Stroke Regulating Valve
Product overview
The SYV77 high-pressure cage regulating valve produced by foreign technology is a pressure-balanced regulating valve. The fluid channel of the valve body is S-streamlined, with small pressure drop loss, large flow rate and adjustable range. Regulating valve with multi-spring film actuator, compact structure, large output force. The valve is widely used in high pressure drop occasions requiring good dynamic stability, low noise and small cavitation corrosion.
