The Sun Hydraulics RVEAOEN (RVEAOEN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when the inlet pressure reaches the valve setting, allowing it to throttle flow and maintain desired pressure levels. It features a vent port that enables remote control by other pilot or 2-way valves, offering flexibility in various applications. The valve is characterized by its accuracy, low pressure rise versus flow, smooth operation, and moderate speed. The RVEAOEN can accept maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such configurations. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. This cartridge is not recommended for load-holding applications due to potential spool leakage. Backpressure on the tank port directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; exposure to petroleum-based fluids can damage these seals. The valve incorporates Sun's floating style construction to minimize internal binding issues potentially caused by excessive installation torque or machining variations. Key specifications include a capacity of 30 gpm (120 L/min), a maximum operating pressure of 5000 psi (350 bar), and a typical response time of 10 ms. The valve features an adjustment screw with an internal hex size of 5/32 in (4 mm) and requires specific installation torques for optimal performance. Weighing just .70 lb (0.30 kg), this model offers reliable performance in demanding hydraulic systems requiring precise pressure control.
