Product Details
SYV76
High pressure low noise cage regulating valve
Linear Stroke Regulating Valve
Product overview
SYV76 high-pressure low-noise cage regulating valve produced by foreign technology is a pressure-balanced regulating valve designed to reduce the noise of compressible fluids. In order to adapt to the throttling and expansion of gas, the sleeve is equipped with many symmetrical holes to reduce the pressure drop, which is lower than the HPN high-pressure cage valve. The valve body has a compact structure, the fluid channel is S-streamlined, the pressure drop loss is small, and the flow rate is large. The regulating valve is equipped with a multi-spring film actuator, which is compact and has a large output force.

Remarks:
1. P = normal temperature type upper valve cover, E1 = extension type upper valve cover.
2. The size of column H on the table is the value of the handwheel mechanism of the river section valve. If the handwheel mechanism is normally installed on the top, the size of the handwheel mechanism should be added accordingly.
The technical parameter table number of the variable HA actuator is NO. AN10-29-2.
