Pneumatic multi-cage high-pressure regulating valve is composed of multistage cage symmetrical hole sleeve flow valve, fully control the flow rate of the medium through the valve, greatly reduce the noise of high pressure gas or steam in the valve, stable multi-level pressure down effective liquid does not produce cavitation, is used in the high pressure medium performance stable control valve, can choose multiple spring pneumatic membrane mechanism or electric actuator.

Simple control, rapid response, and intrinsically safe, do not need to take additional explosion-proof measures. The pneumatic regulating valve is powered by compressed air, to realize the switching volume or proportional adjustment, the source to the cylinder as the actuator, receiving the control signal of the industrial automation control system to complete the adjustment of the pipeline medium flow, pressure, temperature and other process parameters.
