Prince PC Adj. Flow Control Valve: No. WR-1975-30, 0-30 GPM, 3/4” NPT Ports
The W-1900 is a pressure compensated adjustable flow control valve. By rotating the handle, the flow out the “CF” or controlled flow port can 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 be used to power another circuit or can be returned to tank. Once the controlled flow is set, it will remain nearly constant with variations in pressure on either the controlled or excess flow ports. Please note, if during operation the controlled flow port is blocked, the valve will compensate in such a way as to shut off flow to the excess port.The WR-1900 has a built-in adjustable pressure relief. For this model, the excess flow port must be connected to tank. It should be noted that whenever this or any valve is used to bypass or restrict flow, heat will be generated. Steps may be required to keep oil temperature from becoming too high.
