The Sun Hydraulics RVEAQMN (RVEAQMN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve remains normally closed until the inlet port pressure reaches the preset level, at which point it opens to the tank port to maintain consistent pressure. Featuring a vent port for remote control, this model offers accurate performance with low pressure rise versus flow and operates smoothly and quietly with moderate speed. It is capable of handling a maximum operating pressure of 5000 psi (350 bar) and can manage a capacity of 30 gpm (120 L/min). The main stage orifice is safeguarded by a 150-micron stainless steel screen, though it is not recommended for load holding applications due to potential spool leakage. Notably, back pressure on the tank port directly affects the valve setting at a 1:1 ratio. The valve's design incorporates Sun's floating style construction to reduce internal part binding caused by excessive installation torque or machining variations. Cartridges configured with EPDM seals are suitable for systems using phosphate ester fluids but are vulnerable to damage from petroleum-based products. The adjustment mechanism allows for fine-tuning with up to five clockwise turns increasing the setting, while installation requires specific torque settings: 45-50 lbf ft (61-68 Nm) for valve installation and 80-90 lbf in (9-10 Nm) for locknut torque. A typical response time of 10 ms ensures timely operation, while maximum valve leakage is rated at 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). This cartridge weighs approximately .70 lb (.30 kg) and comes with an optional Viton seal kit under part number 990202006.
