K7 Series Unloaders
The unloader valve diverts water flow into bypass when the trigger gun valve is closed.
Flow actuated unloaders divert water to the bypass when there is a sufficient reduction or stoppage of water flow. The flow actuated unloader has an orifice instead of a check valve in pressure actuate unloaders. When the gun valve is closed and water flow stops, system pressure is increased rapidly at all points past the orifice.
A small channel in front of the orifice allows the increased pressure to travel up to the piston assembly, pushing it down. The rest of the water flow is diverted through the bypass and back to the float tank or pump inlet.
