This valve provides a means of sensing the higher pressures between two lines on a hydraulic circuit allowing this line to be used for an auxiliary function, such as the removal of a mechanically applied brake, the operation of a gauge or to give a remote pressure sensing line for the control of another independent valve.
When a higher pressure is sensed at inlet port 1 than at inlet port 3 the ball within the cartridge is forced against a seat opening the higher pressure to outlet port 2.
When the higher pressure appears at inlet port 3 the ball is forced against another seat which blocks inlet port 1 and opens up inlet port 3 to outlet port 2.
