EPOXY Coated Nylon Reinforcement Disc Swing Flex Check Valve 40 degree incline Ductile Iron ​

Description:

    RDCV(Rubber Disc Check Valve) is a fully encapsulated resilient disc seat, double flange swing check valve for reliable reverse flow prevention, good for both clean water/sewage applications. It is a 40 degree angle declined seat which can help quick closure and minimize the water hammer and slamming.

Features:

    A 40 degree angle tilted seat design helps close very soon for shorter stroke and minimize the water hammer and slamming for lower stroke and flap above water flow.

    EPDM rubber coated CS disc is strong with corrosion resistance, with nylon fabric inserted into makes disc hard, which prevents disc from damage and secure longer service life

    Simple design, few internal components and big top cover makes inner cleaning, parts replacement and maintenance easier.

    With big valve body, it keeps 100% full flow area and water head loss is reduced

    Opening pressure only 0.2 bar fits for low pressure sealing test

    DI valve body is 20-30% lighter than CI body and few internal parts easy for equipping and lowering the chances of impediment, the life cycle of RDCV is over 50000 times.

    Meets BS EN 1074-3 and BS EN 558 F/F dimensions.
