The Sun Hydraulics RVGACDV (Material Number: RVGACDV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when inlet pressure reaches the set level, effectively throttling flow to maintain desired pressure. It features a vent port for remote control and offers smooth, quiet operation with moderate response speed. The valve can handle maximum pressure 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, ensuring durability and reliability. This model is not recommended for load-holding applications due to potential spool leakage. The back pressure on the tank port directly influences the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; however, these seals are incompatible with petroleum-based fluids. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. Key specifications include a cavity type T-17A, Series 3 capacity of 60 gpm (240 L/min), and a maximum operating pressure of 5000 psi (350 bar). The typical control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with a response time of approximately 10 ms. Installation requires a torque of 150-160 lbf ft (203-217 Nm), and adjustments can be made using an internal hex screw with five full clockwise turns increasing the setting. This model weighs approximately 1.60 lb (0.70 kg) and comes with Viton seal kit option number 990017006 for enhanced performance under specific conditions.
