Another check valve on the rotary screw compressor is installed just after the compressor component, and as previously explained, this check valve ensures that the compressed air and possible oil mixture does not flow back into the compressor section of the unit. MNPT tank check valves are used to keep air volume and pressure from escaping into the compressor heads while not operating. PSI 250 PSI, Max. There tends to be 2 individual or sets of check valves that are used inside the piston head to control the airflow to and from the compressor cylinder. Since the check valve is a one way valve, once compressed air gets into the compressor tank, in theory, the only way it should get back out, is via the discharge coupler into which you connect your air hose. PSI 250 PSI, Inlet Diameter 0.5 in, Model# s-1093-8", All Rights Reserved. "partNumber": "22779" "externalIdentifier": { Load genie unloads discharge manifold using 3/8in. When the unloader valve opens the compressor pump to atmosphere, if there were no compressor tank check valve, as soon as the compressor stopped and the unloader valve opened, not only would the air bleed off from over the compressor piston, all of the air in the compressor tank would bleed out the unloader valve to atmosphere too.So the check valve essentially stops the compressors air from bleeding off. Since they only allow flow in one direction, a check valve relies on a pressure differential to work.
