  • Wafer Check Valve Application
    Wafer check valves or sometimes called dual plate check valves has the same applications as swing check valves but with added advantageous. The design is lighter and more compact and lighter than a swing check valves, making it easier to install and lead to lower cost overall.

  • Check Valve Application
    Swing check valves are design to close quickly and automaticaly with positive shut off in either horizontal or vertical (flow up) pipe runs. Inherently, swing check valves have a low pressure drop and are best suitable for velocity applications. GLT closure design allows GLT swing check valve to close completely even and remain closed with no flow when installed in a horizontal pipe run.
