Sample Handling

RAVE Diaphragm Valves

For Restek air sampling canisters

  • Proven long life—durable design is engineered to exceed 15,000 cycles.
  • Leak-free performance—each and every valve is helium leak tested to 1x10-6 mL/sec.
  • Effortless operation—easily finger turn to achieve full valve closure (only 10 in-lb).
  • Enhanced damage resistance—W-type valve seats are work-hardened and wetted surfaces contain no moving parts.

RAVEn Diaphragm Valves

For Entech air sampling canisters

  • Easy retrofit—connect to Entech 3.2 L, 6 L, and 15 L air canisters; replace TOV and TOV-2 valves without modification!
  • Proven long life—durable design is engineered to exceed 15,000 cycles; identical internal design to RAVE valves for Restek air canisters.
  • Leak-free performance—each and every valve is helium leak tested to 1x10-6 mL/sec.
  • Effortless operation—easily finger turn to achieve full valve closure (only 10 in-lb).
  • Enhanced damage resistance—W-type valve seats are work-hardened and wetted surfaces contain no moving parts.

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.
