The Wanner A52-1 hydraulic unloader valve is the ideal candidate to tackle the toughest jobs. It features an light weight aluminum alloy casting for superior corrosion resistance. The A52 acts as a pressure regulator by modulating fluid flow through a bypass valve. When the discharge line from the control valve is closed, the flow is diverted past the bypass valve to remove the pressure load from the pump.
