    Characteristics and Application of Pneumatic Double Flange Knife Gate Valve

    The pneumatic gate valve is a more complex automatic control instrument, composed of a variety of pneumatic components and valve body. It is mostly used for occasions requiring quick cut-off and opening.

    Double-acting, two-position control of valve opening and closing.

    Single-acting, (spring return); in the circuit and gas cut off or failure, the valve automatically opens and closes.

    Scope of application

    1. Oil and natural gas transmission pipeline. Flat gate valves with diversion holes also facilitate pipeline cleaning.

    2. Delivery pipelines and storage equipment for refined oil.

    3, oil, natural gas mining wellhead device, that is, Christmas tree valves.

    4. Pipes with medium of suspended particles.

    5. City gas transmission pipeline.

    6. Water works.

    Optional Accessories

    1. Single or double control solenoid valve (24V, 220V and other voltages are available for selection, and explosion-proof solenoid valve can be selected if necessary).

    2, proximity switch.

    3, gas source treatment triplet (including pressure reducing valve, filter valve, oil mist device)

    4, electric/gas valve positioner (adjustable type)
