CGH系列高压套筒调节阀。阀芯为压力平衡式单座结构，带平衡密封环，泄漏等级高，标佳泄漏等级为IVV级可供选择。该系列阀门不平衡力小，可有效克服来自流体的阻力，配置较小执行机构即可获得较大关闭压差，套筒有窗口型多孔型，阀芯有仿形轮廓，可适用于多种高压场合。执行机构标准配置为多弹簧薄膜式，气缸式、电动、液动可供选用。

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.
