The Sun Hydraulics RVGALYN (RVGALYN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve remains normally closed and only opens to the tank port when the inlet port pressure reaches a predetermined setting, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or 2-way valves, offering flexibility and adaptability in various applications. Known for its accuracy, low-pressure rise versus flow, smooth operation, and moderate speed, this cartridge is suitable for use in cross-port relief circuits but not recommended for load-holding applications due to spool leakage. The valve can handle maximum pressure at port 2 and incorporates a 150-micron stainless steel screen to protect the main stage orifice. Its construction minimizes internal binding risks due to excessive installation torque or machining variations. The RVGALYN model can accommodate systems with phosphate ester fluids when configured with EPDM seals; however, contact with petroleum-based fluids should be avoided as it may damage the seals. This cartridge fits into a T-17A cavity and has a capacity of 60 gpm (240 L/min). It operates at pressures up to 5000 psi (350 bar), with control pilot flow ranging from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min). The typical response time is around 10 ms. The valve's maximum leakage at 110 SUS (24 cSt) is specified as 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Adjustment of the setting requires approximately five clockwise turns. Installation torque ranges from 150 to 160 lbf\u00b7ft (203 to 217 Nm), ensuring secure placement within hydraulic systems where precise pressure management is critical.

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- 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.
- 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.
