Sun pressure regulating valve

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.

  • 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.
  • 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. This valve configuration is tested with a 210 bar maximum differential between inlet and reduced 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 350 bar.
  • Pilot operated reducing, reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves.
  • 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.
