New RAVE+ diaphragm valves from Restek offer enhanced features that bring premium performance to air sampling operations.
- Exclusive polymer-free construction means no sample contamination from off-gassing or target compound loss due to adsorption.
- Durable, roller-hardened valve port threads provide superior performance—and every valve is helium leak tested to 1×10-6 mL/sec.
- Rugged, work-hardened, proprietary, all-metal valve seats provide 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.
