Non Return valves are mostly used to maintain flow of water in only one direction and stop the return flow of water. These valves are self operative by pressure only.These valves can be fitted horizontally as well as vertically and are used on main water pipelines.

    Product Details:
    BrandNormex
    Size Range25 mm to 100 mm (Up to 350 mm in Flanged Ends)
    Pressure RatingPN 1.6
    TemperatureUp to 80 C
    InstallationHorizontal or Vertical
    ModelB-06

    Ball Type Check Valves is a non return valve with a very simple and robust design. The heart of the valve is rubber coated ball. The hinge-pin-disc mechanism used in conventional check valves, which is the cause of most operation and maintenance issues such as pressure drop, imperfect sealing, leakage, clogging, etc., is eliminated.

    As the pump starts, the ball moves out totally from the flow path, giving a full bore with maximum flow discharge and minimum head losses. As the pump stops, the ball rolls back and seats perfectly on the rounded valves seat ensuring totally leak proof sealing.

    Salient Features:

    1. Lowest possible pressure drop across all types of check valves.
    2. 100% leak proof sealing years over years.
    3. Non-clogging and self cleaning as ball rotates during operation.
    4. Virtually no wear and tear, no maintenance and longer service life.
    5. Higher solid handling capacity due to full bore and straight internal path.
    6. Lower head loss-high discharge, reduced pumping time - All leading to Energy Savings.

    Applications:

    Clean water, Raw water, Sewage, Slurry, Waste Water, Viscous liquids etc.

    Used in industries like:

    The typical applications are domestic pumping and irrigation systems.

    Silent Check Valves are short length double flanged valves with all the internals designed to be hydrodynamic. When open, these valves have a flow area equal to the nominal bore area. Therefore, unlike other spring loaded valves conventional flapcheck valves, these valves offer lower head losses maintain laminar flow. The valve closes due to return spring force, valve is “Quick Closing”. The valve gets closed before the start of back flow / return velocity. Hence, water hammer is eliminated in most of the cases.

    Features:

    1. Working principal Hydrodynamic guided closing.
    2. The closing mechanism is guided backed with return spring for quick closing, opening and perfect sealing.
    3. Due to Aero/hydro dynamic effect water hammer is eliminated.
    4. Very low pressure loss
    5. Most suitable for clear liquids air.
    6. Silent operation.
