OPERATION

The valve selects the higher of two incoming pressures and ports it to the centre port, while blocking the other inlet port. The valve is normally used in load sense circuits for resolving sensing pressures to be ported to a pump or valve, but there are manyother uses. Note that the centre port is always ported to one of the inlet ports.
