Product Description
Pilot-operated, pressure reducing valves reduce a high primary
pressure at the inlet (port 2) to a constant reduced pressure at
port 1, allowing circuits with multiple pressure requirements to be
operated using a single pump.Full reverse flow from reduced
pressure (port 1) to inlet (port 2) may cause the main spool to
close. If reverse free flow is required in the circuit, consider
adding a separate check valve to the circuit.If pilot flow
consumption is critical, consider using direct acting
reducing/relieving valves.Main stage orifice is protected by a 150
micron stainless steel screen.
Recommended maximum inlet pressure is determined by the adjustment
range. Ranges D, E, N, and Q are tested with a 2000 psi (140 bar)
maximum differential between inlet and reduced pressure. Ranges A,
B, and H are tested with a 3000 psi (210 bar) maximum differential
between inlet and reduced pressure. Ranges C and W are tested with
5000 psi (350 bar) of inlet pressure.
Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable and have low hysteresis.Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).Pilot operated reducing, reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves.W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.All three-port pressure reducing and reducing/relieving cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size). When considering mounting configurations, it is sometimes recommended that a full capacity return line (port 3) be used with reducing/relieving cartridges.Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
