How it work:
By rotating the handle, the flow out the "CF" or controlled flow portcan be varied within the range given in the chart below. Any remaining flow is bypassed to the "EF" or excess flow port.
This flow can beused to power another circuit or can be returned to tank. Once the controlled flow is set, it will remain nearly constant with variations inpressure on either the controlled or excess flow ports.
Please note, if during operation the controlled flow port is blocked, the vave wicompensate in such a way as to shut off flow to the excess port.
This valve can also be used as a restrictive flow control by plugging the excess flow port.
Attention:
The WR-1900 has a bult-in adjustable pressure relief. For this model, the excess flow port must be connected to tank.It should be notedthat whenever this or any valve is used to bypass or restrict flow, heat will be generated. Steps may be required to keep oil temperaturefrom becoming too high.
