    The document summarizes the features and operation of an automatic pinch valve. The valve consists of a cylindrical rubber sleeve within a valve body that closes when pressure is applied between the sleeve and body. It allows direct flow without head loss or blocking, even with viscous or abrasive liquids. When pressure is removed, the sleeve opens and flow resumes with no moving parts requiring maintenance. Technical specifications are provided for body materials and dimensions for PVC and cast iron valves in various pipe sizes.

    FEATURES
    - Direct flow with no loss of head.

    - Bubble free tightness even with the wettest liquids.

    - Viscous or paste-like liquids pass with no choking or blocking.

    - Abrasive material cause no damages.

    - No moving parts; hence no maintenance

    - Self-cleaning; will not jam or seize

    PRINCIPLE OF OPERATION

    The automatic Pinch Valve comprises valve body a cylindrical sleeve made
    from natural rubber and two flanges. Valve is closed by applying pressure
    between the body and the sleeve via air connection port. Usually pressure is
    applied by air or water. Sleeve deforms when the pressure is applied and
    closes the valve. Fibre reinforcement in the construction of the sleeve ensures
    total bubble tight shut oft.
