    Kamvalok® Flat-Face Coupler and Adaptor

    The new Kamvalok® Flat is the next generation of OPW dry-disconnect couplings. We’ve taken our proven, best-in-class Kamvalok and flattened the connection points. This effectively eliminates all cavities where liquid can pool and subsequently spill upon disconnection.

    Features & Benefits

    • Reduce product loss at disconnect by up to 85%
    • New patent-pending smooth, flat-face poppets
    • Industry-standard locking handle
    • Easy to close Autolok™ locking arms
    • Automatic locking arms, no pins or buttons
    • Vibration-resistant Twin-Kam™ arms

    Operation

    OPW Engineered Systems Kamvalok® Dry Disconnects are easy to operate. Connections and disconnects are accomplished by simply closing and opening two cam arms which lock into the machined groove around the circumference of the mating adaptor. The adaptor contains a spring- loaded poppet assembly that is actuated by the handle-action on the coupler.
