The Sun Hydraulics RVEAMSV (RVEAMSV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the pre-set level, allowing it to throttle flow and maintain desired pressure levels. It features a vent port 3 for remote control via other pilot or 2-way valves, ensuring enhanced control flexibility. The valve is characterized by its accuracy, low pressure rise versus flow, smooth operation, quiet performance, and moderate speed. It can accept maximum pressure at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen; however, this valve is not ideal for load-holding applications due to potential spool leakage. Back pressure on tank port 2 directly affects the valve setting at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but are incompatible with petroleum-based substances. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variances. The RVEAMSV has a cavity type T-2A and a series capacity of 30 gpm (120 L/min). Factory settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min) with a typical response time of about 10 ms. Maximum valve leakage is measured at three in\u00b3/min under specific conditions. The adjustment requires up to five clockwise turns to increase settings, and installation torque ranges from 45-50 lbf-ft (61-68 Nm). The model weighs approximately .70 lb (.30 kg) and features Viton seals as part of its construction options.
