RAVE+ Diaphragm Air Valves

For Restek air sampling canisters
  • Exclusive polymer-free construction means no sample contamination from off-gassing or target compound loss due to adsorption.

  • Rugged, work-hardened, proprietary, all-metal valve seat provides protection against particles that cause leaks.
  • VOC-free, thread-locking adhesive keeps valve knob securely in place.
  • Hard-stop design prevents users from overturning the valve and locking it open.

RAVE+ diaphragm valves offer enhanced features that bring premium performance to air sampling operations. Unlike competitor valves that contain soft polymeric materials, RAVE+ valves have a 100% stainless-steel construction, which eliminates sample contamination from off-gassing, prevents target compounds from being lost due to adsorption, and ensures a longer service life. The valve port threads are roller hardened to increase durability, resist damage, and prevent leaks. Rugged, work-hardened, proprietary, all-metal valve seat provides protection against particles that cause leaks. In addition, a VOC-free, thread-locking adhesive prevents the valve knob from loosening and ensures it stays securely in place. RAVE+ valves also now feature a built-in hard stop that prevents users from turning the knob too far and locking the valve open. As a final measure to ensure reliable performance, every RAVE+ valve is helium leak tested to 1x10-6 mL/sec prior to shipping. With these enhanced features, RAVE+ diaphragm valves build on the high-quality standard of original RAVE valves and provide superior performance for air sampling.
