XG Pneumatic Cage Guided Type Control Valve

ZXG Pneumatic Cage Guided Type Control Valve is a pressure-balanced valve, equipped with cage guided single seat seal structure, a multi-spring actuator, and Import MA43 Series Balance Seal ring; the stream flow channel was streamlined. It has the advantages of stable flow, accurate flow characteristics, low noise and so on. It is applicable to small leakage and the working place of large pressure differential.
