The Sun Hydraulics RVGDCWV (RVGDCWV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed for precise pressure regulation. This normally closed valve opens to tank port 2 upon reaching the set pressure at inlet port 1, effectively throttling flow to maintain desired pressure levels. It features a vent port (port 3) for remote control and a drain port (port 4) that ensures insensitivity to back pressure. The valve is known for its accuracy, low-pressure rise versus flow, smooth operation, and moderate speed. It can handle maximum pressures at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. However, this valve is not recommended for load-holding applications due to potential spool leakage. The pressure at port 4 directly adds to the valve setting at a 1:1 ratio but should not exceed 5000 psi (350 bar). The RVGDCWV incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or cavity/cartridge machining variations. This cartridge fits into cavity T-23A, Series 3, with a capacity of up to 60 gpm (240 L/min) and factory pressure settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar), with control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min). Typical response time is around 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is approximately 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Adjustment requires up to five clockwise turns, with specific torque requirements detailed for installation and adjustment components. The model weighs approximately 1.60 lb (0.70 kg) and utilizes Viton seals in its cartridge design.
