    ZMAS Pneumatic Membrane High Pressure Angle Type Control Valve
    ZMAS Pneumatic Membrane High Pressure Angle Type Control Valve

    ZMA / BS-220, 320 series pneumatic thin instant angle type commercial pressure regulating valve is composed of pneumatic Mengqiang multi-ballistic actuator and angle type pressure relief valve.
    ZMAS high pressure angle high pressure regulating valve adopts permeable seat structure, which is easy to replace and has good sealing performance. The spool is plunger-shaped. It is used for interrogating the core under the condition of differential pressure. The tungsten-cobalt alloy is deposited on the head.
    Widely used in chemical industry, oil refining and other industries, especially suitable for synthetic nitrogen and urinary industry commercial pressure and commercial pressure differential media regulation.
