Model RD500 Adjustable Flow Divider Valve

30 GPM

Prince _Valve _Hydraulic _Adjustable Flow Divider _RD500 FUNCTION

The PRINCE model RD-500 is an adjustable constant volume priority divider. This valve provides the same function as the PRINCE model RD-400 except the priority flow is adjustable from 2 GPM to 12 GPM. The priority flow is set using the adjusting screw and is then locked in place to maintain setting. This allows setting to be fine tuned in the field to the exact flow needed.

Model RD100 Flow Control Valve

30 GPM

Prince _Valve _Hydraulic _Flow Control _RD100

FUNCTION

The PRINCE valve is a pressure compensated adjustable flow control valve. By rotating the handle, the flow out the "CF", or controlled flow port, can be varied from approximately 0 to the maximum controlled flow shown 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.

Model RD-1400 Lock Valve

30 GPM

Prince _Valve _Hydraulic _Lock _RD1400 FUNCTION

The PRINCE valve model RD-1400 is a double pilot-operated lock valve. This valve will lock a cylinder in place when a directional control valve is in the neutral position. In operation oil is directed to one of the valve ports and oil can free flow to the corresponding cylinder port. The pressure on this valve port will shift the pilot spool opening the opposite check valve. This will allow oil to return through the opposite check valve. This valve has a hardened steel seat and steel ball and therefore should not be used in applications requiring absolutely zero leakage. When using a pilot operated check to lower a heavy load the valve may chatter. An orifice in the line in some cases may be beneficial.

Model RD200 Proportional Divider Valve

30 GPM

Prince _Valve _Hydraulic _Proportional Divider _RD200 FUNCTION

The PRINCE model RD-200 valve is a pressure compensated proportional flow divider. The standard models of this valve will take one inlet flow and split it into two nearly equal outlet flows. The valve is also available with special ratio spools which will split the flow into two flows proportional to the ratio specified. Because the valve is pressure compensated the valve will maintain the divider ratio with quite different loads on the outlet ports as long as the inlet flow is within the range given in the chart below. Flow through the RD-200 cannot be reversed.

Model RD400 Fixed Flow Divider Valve

30 GPM

Prince _Valve _Hydraulic _Fixed Flow Divider _RD400 FUNCTION

The PRINCE model RD-400 is a constant volume priority divider. It can be used in applications where two circuits are to be supplied by a single pump such as power steering systems. In operation the flow of oil supplied to the inlet is divided into two flows, the priority flow and the excess flow. The priority flow will remain nearly constant with variations in pressure on either the priority or excess flow port and will also remain nearly constant with variations in the inlet flow.

The priority flow GPM is determined by a fixed orifice inside the main spool. The desired priority GPM must be specified with model number, see below. The PRINCE model RD-400R provides the same function as described above with the addition of a built in pressure relief for the priority port only. This relief is internally adjustable and requires a separate line to tank. The relief is factory set at 1,500 PSI.

Model RD500P Proportional Flow Divider Valve

30 GPM

Prince _Valve _Hydraulic _Proportional Flow Divider _RD500P FUNCTION

The PRINCE model RD-500P is a pressure compensated proportional flow divider valve with one fixed and one adjustable orifice. This valve will take one inlet flow and split it into two nearly equal outlet flows, the adjustable orifice allows the divider ratio to be changed in the field. Because the valve is pressure compensated the valve will maintain the divider ratio with quite different loads on the outlet ports as long as the inlet flow is within a given range.

Model RD1000S Sequence Valve

30 GPM

Prince _Valve _Hydraulic _Sequence _RD1000S FUNCTION

The PRINCE valve model RD-1000S is an internally piloted adjustable sequence valve. This valve will prevent the flow of oil from going to the sequence port until the pressure on the inlet port reaches the sequence pressure. The sequence pressure is adjustable within the range given in chart below. A built in check valve allows flow from sequence port to inlet. To operate properly the drain port must be connected to tank. This valve is a spool type sequence valve and will provide smooth operation but should not be used in applications that require low leakage.

Wolverine Adjustable Flow Control Valves

Wolverine Adj Flow Control

The PRINCE valve model 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.

This valve can also be used as a restrictive flow control by plugging the excess flow port.

The PRINCE valve model 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 these 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.
