    Quick details

    Light weight, versatile design, 80 to 90% lighter than conventional full-body check valves.

    Reduces pipe supports, simplifies piping, easier, less costly installation.

    Reduced thermal and seismic considerations.

    No need for additional expensive support.

    Optimum space utilization; simplified piping.

    Spring-loaded, double door design has low cracking pressure.

    Discs open 85° to ensure positive closing.

    Materials and trims available for all services within temperature range.

    Extended leg springs prevent seat wear caused by scrubbing.

    Springs are precisely calculated to increase the responsiveness of the disc, thus reducing damaging effects of water hammer.

    Resilient or metal-to-metal seat available.
