    1. Check valve is a valve that prevents the fluid from flowing back and ensures to flow in only one direction.

    2. It can be used to prevent the flow less from returning avoid pipe-hammering.

    3. It is used in the food processing,beverages, wine, oil,cosmetics, pharmaceutical and chemical industries.


    Operating Principle

    The valve opens when the pressure of the fluid exceeds the pressure to spring, When the two pressures are equalised, the valve closes, A stronger counter – pressure also makes the valve close.


    Sanitary Check Valves can be installed horizontally or vertically. However, the following specifications must be followed for ball and disk check valves:

    – Ball Check Valve –

    In a vertical setting, the product has to flow from bottom to top so that gravity can push the ball in and out of the seat.

    In a horizontal setting, the curved portion of the valve needs to be upright and at 90 degrees to the pipe. This makes sure that the valve is free-draining and the ball sits properly.

    – Disk Check Valve –

    Disk Check Valves are not free-draining in a vertical setting. Therefore, for them to be free-draining, they need to be in a horizontal position.
