Item # Check Valve, Regenerative Blower Accessories
Check valves will be required in applications where two or more blowers are used, and one blower is not in operation. If one blower is not operational, the check valve will prevent air flow through that blower, which would otherwise divert flow from the system. Check valves have double butterfly-style flappers with BUNA-N seals. The valves offer low flow resistance and positive sealing, and are offered with standard M. NPT connections, or optionally with flanged or plain ends (for hose clamping).
