HIGH PRESSURE FLUID SPRAY NOZZLE INCORPORATING A FLOW CONTROLLED SWITCHING VALVE
A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. A mid portion of the body has at least one passage therein leading from a central axial bore to one or more external ports each having a tractor nozzle. The valve outlet connects the axial bore to a cleaning nozzle. A poppet member is received in the central axial bore. In a first position, the poppet member directs fluid flow through the outlet to the cleaning nozzle connected to the outlet. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the tractor nozzles. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.
