Kamvalok® Flat-Face Coupler and Adaptor

Flat-Out Better Spill Prevention

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.
