The Sun Hydraulics RVGACKV (RVGACKV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed pressure regulating valve opens to the tank port when the pressure at the inlet port reaches a predetermined setting, effectively throttling flow to maintain desired pressure levels. It features a vent port that enables remote control by other pilot or two-way valves, enhancing its versatility and control capabilities. The RVGACKV is known for its accuracy, low-pressure rise versus flow characteristics, smooth operation, and moderate response speed. This valve can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. It includes a 150-micron stainless steel screen protecting the main stage orifice and is not recommended for load-holding applications due to potential spool leakage. Back pressure on the tank port directly affects the valve setting at a 1:1 ratio. The cartridge is equipped with EPDM seals for compatibility with phosphate ester fluids but must avoid petroleum-based substances to prevent seal damage. The RVGACKV incorporates Sun's floating style construction to reduce risks of internal binding from excessive torque or machining variations during installation. It fits into Cavity T-17A and has a series 3 capacity of up to 60 gpm (240 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time around 10 ms. The valve's maximum leakage rate under specified conditions is 4 in\u00b3/min (65 cc/min). Installation requires specific torque settings, and adjustments are made via an internal hex screw with a locknut for secure positioning.

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.
