RAVEqc Quick-Connect Air Valves

  • Simplify your workflow—tool-free design makes it fast and easy for anyone to make consistent, quality connections.
  • Extend air canister and valve lifetime—no wrenches mean no overtightening or cross-threading damage.
  • Stand-alone or supporting roles—use alone or pair with a bellows/diaphragm valve for the ultimate in sample security and convenience.
  • Check status at a glance—if the parts are connected, the valve is open; if they’re apart, it’s closed. (Open-position valves also available.*)
  • Standard compression or tube end fittings accommodate a wide variety of air canisters and related devices.
  • Leak-free performance—each and every valve is helium leak tested to 1x10-6 mL/sec.
  • Compatible with Entech Micro-QT valves.

Note: A RAVEqc valve bracket is required for use with Restek 1, 3, 6, and 15 L air sampling canisters when using the compression fitting mounted directly on the 1/4" canister tube stub. This bracket is not needed when using Restek miniature canisters or Entech canisters.

** Flow rates calculated on a 1/4" platform.

* Open-position option available to prevent vacuum/pressure from being trapped by the valve when desired (e.g., when using a vacuum/pressure gauge). High flow facilitates use with canister-cleaning ovens.
