HCB Pneumatic Cage Type Double-Seat Globe Control Valve

HCB Pneumatic Cage Type Double-Seat Globe Control Valve adopts the cage guided structure and pressure balanced plug. Different from Cage Type Single-Seat Type, this kind of control valve adopts the cage type double-seat structure and is mainly used in applications that do not have high requirements for shut-off class. As it adopts the double-seat structure, and the two sealing faces are metal seals, the temperature range is wider. The plug makes use of the pressure balanced structure, 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. It is widely used for fluid control on pipelines of middle and low temperature and middle and low pressure that require good dynamic stability. With such features as good sealing performance, high allowable differential pressure, cage guiding, large guiding area, good stability and compact structure, it can realize fast replacement of trims on the line with high maintenance efficiency, saving manpower and time. The balanced plug structure makes sure that the actuator thrust required is the lowest.
