Diaphragm Valves for Premium Air Sampling Performance

Jan 05 2022

New features and improved performance for air sampling operations

RAVE+ diaphragm valves from Restek offer enhanced features that bring premium performance to air sampling operations. Unlike competitor valves that contain soft polymeric materials, RAVE+ valves are 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 seats provide 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.

Now standard on our full line of SilcoCan, TO-Can, and miniature air sampling canisters, these newly redesigned, American-made valves are also ideal for upgrading existing canisters. Rugged, all-metal RAVE+ valves can be ordered with Siltek treatment for added inertness and with either two or three ports to accommodate an optional gauge. Diaphragm rebuild kits and RAVE+ guards are also available to further extend the life of these long-lasting air valves.
