The Sun Hydraulics RVEACMV (RVEACMV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. When the inlet port 1 pressure reaches the valve's preset level, it opens to tank port 2, throttling flow to maintain stable pressure. The valve features a vent port 3 for remote control via other pilot or 2-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. It allows maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen but is not recommended for load-holding applications due to potential leakage. The valve's performance is influenced by back pressure on tank port 2, which adds directly to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but can be damaged by petroleum-based substances. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 30 gpm (120 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge offers factory pressure settings established at 4 gpm (15 L/min). It features a response time of approximately 10 ms and maximum leakage of three in\u00b3/min at 1000 psi (50 cc/min at 70 bar). The installation requires specific torque settings: valve hex size is 1-1/8 in. (28.6 mm) with an installation torque range of 45-50 lbf ft (61-68 Nm), while the adjustment screw has an internal hex size of 5/32 in. (4 mm), and locknut hex size is 9/16 in. (15 mm) requiring torque of 80-90 lbf in. (9-10 Nm). The model weighs .70 lb (.30 kg), and Viton seal kits are available under part number 990202006.
