High Pressure Cage Guided Control Valve has a cage type guiding and pressure balanced plug, it is mainly used in applications that have high working pressure. The sealing ring is metal, if the soft sealing ring is used then it will be have better leakage class, or use metal seal ring for wider working temperature range. Pressure balanced structure to be used so the opening and closing force is low and the media under service conditions with high differential pressure can be controlled through relatively low actuator thrust.
High pressure cage guided control valve has multiple types of valve trim, which can be widely used to reduce noise, pressure and flow conditions, it can effectively reduce the impact of cavitation and flashing. It is a highly demanding control elements in industrial process control.
