Product Description

CGH Series High Pressure Cage Control Valve

CGH Series High Pressure Cage Control Valve features pressure balanced single seated plug, balance seal ring and high leakage level, with standard leakage level IV and V for optional.

Moreover the series has small unbalanced force, which can effectively overcome the resistant force of the fluid; therefore smaller actuators can be configured to achieve higher shut-off differential pressure. Windows and multi-hole cage types and contoured-p trim type can be provided for different kinds of conditions.

The standard actuator configuration is multi-spring diaphragm; other actuator types such as cylinder, electric and hydraulic are also available.
