Waukesha Cherry-Burrell brand 62B Air Blow Check Valves are ‘plug-style’, where air pressure pushes the bonded rubber plug away from the seat. In the absence of air pressure, the spring returns the plug and holds it closed against the seat.

For 3-A applications the Waukesha Cherry-Burrell brand 62B Air Blow Check Valve must be used with the incorporated filter disc and suitable air to be in contact with product.

Air usage: estimated air volume usage will depend upon the pipeline vessel to be evacuated. The Waukesha Cherry-Burrell brand 62B is rated up to 1600 Ft3/Hr. (488 m3/Hr.) air flow.
