The Sun Hydraulics RVEAKQN (Material Number: RVEAKQN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. These valves are normally closed and begin to open when the inlet port pressure reaches the valve setting, directing flow to tank port 2 to maintain the desired pressure. Featuring a vent port for remote control by other pilot or 2-way valves, this model is known for its accuracy, low pressure rise versus flow, smooth operation, and moderate speed. The valve can accept maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. It features a main stage orifice protected by a 150-micron stainless steel screen but is not recommended for load-holding applications due to potential spool leakage. Back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are designed for systems using phosphate ester fluids; exposure to petroleum-based products will damage these seals. The Sun floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. With a capacity of 30 gpm (120 L/min), the model operates at pressures up to 5000 psi (350 bar). Control pilot flow ranges from 10\u201315 in\u00b3/min (0.16\u20130.25 L/min), with typical response times around 10 ms and maximum valve leakage of 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). The adjustment mechanism allows five clockwise turns to increase settings, with specific torque requirements for installation and adjustments provided in detailed specifications.
