Pneumatic angle seat valve

  • Working principle

    Valve stays closed(open)by spring force in its offwork state.When piston is actuated by compressed air,valve becomes opened(closed).For double acting type,valve is opened and closed by compressed air.

  • Application range


    Textile dyeing





    EPS molding


    other ...

  • Characteristics

    1. The lower sealing structure can reduce the residue and is easy to clean

    2. Large flow, small flow resistance, no water hammer

    3. Y-shaped design, increase flow by 30%

    4. Long service life

    5. Valve stem automatic calibration, self-lubricating, maintenance-free

    6. The cylinder is made of stainless steel, which is more excellent in harsh environments and can rotate 360 °
