The Sun Hydraulics RVEAQGV (RVEAQGV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. It operates as a normally closed pressure regulating valve that opens to tank port 2 when the inlet port 1 pressure reaches the valve setting, allowing flow throttling to maintain the desired pressure. This model features a vent port 3 for remote control via other pilot or two-way valves and is known for its accuracy, low-pressure rise versus flow characteristics, smooth operation, and moderate speed. The RVEAQGV can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. It includes a main stage orifice protected by a 150-micron stainless steel screen but is not recommended for load-holding applications due to potential leakage. The valve's back pressure at tank port 2 adds directly to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based substances will damage these seals. The Sun floating style construction minimizes internal component binding due to excessive installation torque or machining variations. Key specifications include a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), control pilot flow of 10-15 in\u00b3/min (0.16-0.25 L/min), typical response time of 10 ms, and maximum valve leakage of 3 in\u00b3/min at 110 SUS (24 cSt). Installation requires specific torque settings and hex sizes for adjustment screws and locknuts. The model weighs .70 lb (0.30 kg) and uses Viton seal kits like the part number 990202006 for maintenance or replacement needs.
