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.

    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.
