The AirPro Max® Series WCV Combination Air Valve combines the functions of both the Air Release Valve and Air Vacuum Valve.
Our Series WCV Combination Valve allows a large volume of air to be vented when filling, or a large volume of air intake when draining the pipeline. The Combination Air Valve also vents small pockets of air that accumulate after the line is filled, pressurized and operating. Series WCV Combination Air Valves are offered in both single body and dual body designs.
