The Sun Hydraulics RVGACCN (RVGACCN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve remains normally closed until the inlet port pressure reaches the preset limit, at which point it opens to tank port 2 to throttle flow and maintain regulated pressure. Featuring a vent port (port 3), it allows for remote control via other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. It accepts maximum pressure at port 2 and is suitable for cross-port relief circuits, though users should consider spool leakage in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, but the valve is not recommended for load holding due to potential spool leakage. Back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, EPDM seals are available; however, these seals can be damaged by petroleum-based substances. The valve incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations in cavities or cartridges. With a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model offers typical response times of 10 ms and minimal leakage rates under specified conditions. It requires specific installation torques and adjustments for optimal performance, making it suitable for applications demanding reliable pressure control with remote operation capabilities.

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.
