OPW Kamvalok® Dry Disconnect Couplings are considered the standard of the industry. Used at liquid transfer points where product loss could occur, OPW Kamvaloks® provide a reliable solution to prevent spillage during connection or disconnection. OPW Kamvalok® Dry Disconnect Couplings are used by manufacturers of paint, lacquers, inks, adhesives, fatty acids, pharmaceuticals, liquid soaps, and many other liquid products. They are particularly well suited for handling petroleum products, solvents, ag-chemicals, vegetable oils, detergents and many acids and caustics.

Features & Benefits

Available in 1½”, 2” & 3” Sizes
Stainless Steel and Aluminum materials of construction
Equipped with Autolok® Locking Arms
Features Poppeted Seal Cylinder with Snap-on Nose Seal
Simple Cam and Groove Design with Lever Actuation
360° Orientation – coupler can be connected in any orientation onto the adaptor.
Manufactured in compliance with the highest quality standards of design, materials and construction.
Spill Protection – Helps to reduce the hazards involved in the connection/disconnection process of transferring hazardous materials.
Added protection – Autolok™ locking arms with an automatic locking mechanism signaled by a positive click. Uncoupling requires only an easy tug on the lock release.
Dual protection – poppeted seal cylinder with snap-on nose seal provides automatic closure from both directions – the coupler and the adaptor – to prevent accidental spills. Nose seal can be easily replaced without need for new seal cylinder.
Provides Total Closed-Loop Loading Capabilities by keeping hazardous liquids and vapors in-line and out of the environment.
Ease of Use – The simple connection and disconnection design and lever actuated internal poppet configuration makes this the first choice for liquid transfer operations.
Lever Actuation – The open/close lever action helps to ensure that liquid flow can only begin once the coupling and adaptor are securely coupled. The lever provides for smooth opening and closing even for high pressure applications.

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.
