The Model DS 2-Position Double Selector Valve directs the flow of hydraulic oil to two separate circuits. This permits operation of two double-acting cylinders with one four-way control valve or four single-acting cylinders with two three-way control valves. The hydraulic circuit which is to be operated should be selected before pressure is applied. Valve is of the open crossover type. As spool is moved and one set of outlet ports start to close, the other set of outlet ports start to open.
The Prince DS Valve is a manual 6-way, 2 position double selector valve. This valve will divert the flow going to two separate hydraulic circuits. For example, two double acting cylinders or two reversible hydraulic motors can be operated by one four-way valve. When the double selector spool is pushed in, the top ports are connected to the right ports. When the selector spool is pulled out, the top ports are connected to the left ports. An optional series/parallel spools is also available. This spool will run two reversible hydraulic motors in series when the spool is out and in parallel when the spool is pushed in.
LO Lock Valves are designed to lock a cylinder, or part of a circuit, without leakage while a control valve is in a neutral position. Lock Valves function as check valves, allowing flow to a cylinder and blocking reverse flow until pilot pressure is applied to "unlock" the circuit. These valves may be used to prevent movement of a load while the pressure source is inactive.
SAE 1/4" blade terminals standard.
The Model PD, Proportional-Type, Pressure-Compensated Flow Divider offers an efficient means of proportionally dividing a single flow of hydraulic oil. The flow ratio from the outlet ports remains constant despite load differences between the ports. Outlet flow ratios are preset at the factory and a range of ratios from 50/50 to 90/10 are available. Flow through the Model PD Divider cannot be reversed. It is a flow divider only - not a flow combiner. A Model PDC with a combiner feature is offered by substituting a combiner spool assembly for a standard spool. This feature not only divides flow, but flow may be combined in reverse direction and synchronized in both directions. It is only available with a 50/50 flow dividing ratio. Neither model, however, should be constructed as a flow regulator. If other ratios are required with the combiner feature, contact us.
The 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 sytems. 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 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 factory set at 1500 psi.
The RD-500 is an adjustable constant volume priority divider. This valve provides the same function as the 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.
The RD-500P is a pressure compensated propertinal flow divider with one fixed and one adjustable orifice. On this valve, the divider ratio can be changed in the field.
The Model LT & LTF Valves will operate satisfactorily when installed in any position. These valves may be used as Line Check Valves, permitting full flow of hydraulic oil in one direction only.
Models S & SM offer a simple method of directing system flow to one or the other of two separate lines. An example of this is the operation of two single-acting cylinders, independent of each other, with one three-way control valve. Since the S & SM spools are of open-crossover design, they should be shifted before pressure is applied.
Economically designed for effective control of air and hydraulic fluids where frequent adjustment is not required.
