The Sun Hydraulics PPHBLAV (PPHBLAV) is a pilot-operated, pressure-reducing and relieving valve designed to maintain a constant reduced pressure at port 1 while providing a full-flow relief function from port 1 to tank port 3. This valve is ideal for applications requiring stable pressure control with low hysteresis, making it suitable for systems where precise pressure regulation is critical. The valve can handle a maximum operating pressure of up to 5000 psi (350 bar) and exhibits exceptionally flat pressure-flow characteristics, ensuring reliable performance across various conditions. The PPHBLAV model features adjustable settings, allowing users to fine-tune the valve's performance according to specific system requirements. It incorporates Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations. The valve is equipped with EPDM seals, making it compatible with systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it may damage the seals. For optimal performance, this valve should be used in applications where fast response times are not a priority; in such cases, direct-acting valves might be more appropriate. The PPHBLAV allows for full reverse flow from reduced pressure port 1 to inlet port 2, although incorporating a separate check valve is recommended if reverse free flow is necessary. This model also provides flexibility in mounting configurations and can be physically interchanged with other three-port reducing and reducing-relieving cartridges of the same frame size. It offers a capacity of up to 40 gpm (160 L/min) and includes features like an internal hex adjustment screw and locknut for secure settings adjustments.

Pilot-operated, pressure reducing/relieving valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3).

  • Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 3000 psi (210 bar).
  • Maximum pressure at port 3 should be limited to 3000 psi (210 bar).
  • 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.
  • 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.
  • 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.
  • 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.
