This is a flow-actuated unloader that is designed for any pump that fits within the flow and pressure range of the unloader. The unloader regulates the flow in the system and maintains system pressure via an adjustable nut that controls the amount of tension on a pressure spring. When no flow is going out the outlet port, all flow is diverted to the bypass port at virtually no pressure. The unloader does not “trap” pressure, so it eliminates the need for an easy start valve and virtually eliminates the “kick-back” (that occur with pressure-actuated type of unloaders) upon start up.
