Speck Unloader Valves

Speck Unloader valves should be used to protect the pressure washer pump. The full flow from the pump must pass through the unloader valve for satisfactory operation. Should the actual operating pressure exceed that of the adjusted pressure the unloader valve will act as a pressure regulator, bypassing excess fluid to ensure the adjusted pressure is not exceeded. The valve will switch to pressure-free bypass when the spray gun is shut off and the line pressure between gun and valve remains dormant. The valve can be used to control several spray guns simultaneously. Several pumps can also be connected to a common discharge line.
