CGH Series High Pressure Cage Control Valve

Price Negotiable
Price: Negotiable
MOQ: Negotiable
Delivery Time: 7 - 15 days for small orders. 15 - 30 days for large orders
Brand: WEYO
Product Description
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.
