    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.


    Things to Keep in Mind When Installing a Sanitary Check Valve


    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.
