Multi Stage Cage Guided Control Valves
This multi-stage cage-guided control valve adopts multi-stage stacked cage trim, which realizes step-by-step pressure reduction. It effectively suppresses cavitation, noise and high-velocity erosion under ultra-high differential pressure conditions. Fitted with intelligent electric actuator with local display and handwheel, it accepts 4-20mA control signal and valve position feedback. Widely used in power, thermal power, boiler feedwater and high-pressure process systems.
