Description
Centrifugal Unloader Valve Assembly with weights.
The Centrifugal Unloader Valve Assembly keeps the pump unloaded during startup so the motor can come up to speed without fighting compression. Once the flywheel reaches operating RPM, centrifugal force moves the weights outward, closing the unloader and allowing the pump to begin compressing air.
