Pneumatic cage guide high pressure control valve is mainly composed of valve body, spool, seat and an actuator. Its working principle is to use a pneumatic actuator to drive the valve spool to reciprocate in the valve seat, changing the cross-sectional area of the fluid channel, thereby achieving fluid flow and pressure regulation.
