The Sun Hydraulics RVGACGV (Material Number: RVGACGV) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure in hydraulic systems. It remains normally closed until the inlet port pressure reaches the valve setting, at which point it opens to the tank port to throttle flow and maintain pressure. This model features a vent port for remote control via other pilot or 2-way valves, ensuring precise operation with low pressure rise versus flow. The RVGACGV is suitable for cross-port relief circuits and can handle maximum pressures at port 2, though users should consider spool leakage in such applications. A stainless steel screen protects the main stage orifice, but it's not recommended for load-holding due to potential leakage. This cartridge incorporates Sun's floating style construction, minimizing internal binding from installation torque or machining variations. The back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; however, these seals should not be exposed to petroleum-based substances as they may incur damage. The RVGACGV fits into a T-17A cavity and supports up to 60 gpm (240 L/min) with factory pressure settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with a control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). Typical response time is around 10 ms with maximum valve leakage measured at 4 in\u00b3/min under specific conditions. Adjustments are made by turning clockwise up to five times, and installation torque ranges between 150-160 lbf\u00b7ft (203-217 Nm). The model weighs approximately 1.60 lb (0.70 kg), and Viton seal kits are available for maintenance needs.
