The Sun Hydraulics RVEAOLV (RVEAOLV) is a ventable, pilot-operated, balanced piston relief cartridge designed to function as a normally closed pressure regulating valve. When the inlet port pressure reaches the set threshold, the valve opens to the tank port, throttling flow to maintain regulated pressure. This model features a vent port allowing for remote control via other pilot or 2-way valves and is known for its accuracy, low pressure rise versus flow, and smooth operation. The RVEAOLV can handle maximum pressures at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, although this valve is not recommended for load-holding applications due to potential spool leakage. Back pressure on the tank port directly affects the valve setting at a 1:1 ratio. The cartridge's EPDM seals are compatible with phosphate ester fluids but will degrade if exposed to petroleum-based substances. It incorporates Sun's floating style construction to mitigate internal part binding from excessive installation torque or machining variations. With a cavity size of T-2A and series 2 capacity of 30 gpm (120 L/min), this model operates at a maximum pressure of 5000 psi (350 bar). Its control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), with a typical response time of 10 ms and maximum valve leakage of 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). Installation requires specific torque settings and hex sizes for adjustment screw and locknut components. Overall, the Sun Hydraulics RVEAOLV offers reliable performance in applications requiring precise pressure regulation with remote control capabilities while maintaining robustness against installation variances.
