k5.3 flow actuated unloader 6.6-10.8 gpm 1450-3000 psi 

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 actuated 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. 


features all stainless and brass internal parts 

no external moving parts or springs 

unique balance nozzle principle: eliminates high pressure in all lines while unit is in bypass mode. 

eliminates pressure peaks normally generated by conventionally designed unloaders 

unique unbalanced piston design permits precise pressure adjustment 

mounts in discharge line; flow through design 

convenient bypass location 

dual gauge ports
