Features & Benefits
  • 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.
  • SST locking handle locks in position to prevent accidental opening or closing of valve.
  • Autolok™ locking arms provide added protection with an automatic locking mechanism signaled by a positive click. Release requires only an easy tug on the lock release.
  • Provides for total closed-loop loading capabilities, keeps hazardous liquids and vapors inline and out of the environment. Provides automatic closure from both directions – the coupler and the adaptor – to prevent accidental spills.
  • Safe and easy maintenance, unique stuffing-box design makes disassembly/maintenance quick and easy.
  • Can be coupled in any orientation - 360°
  • Automatically shuts off flow if accidental disconnect occurs

Operation

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.
