The Sun Hydraulics RVEAMVN (RVEAMVN) 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 its set threshold, at which point it opens to tank port 2 to manage flow and stabilize pressure. It features a vent port 3 for remote control via other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, the RVEAMVN operates smoothly and quietly with moderate speed. It is capable of handling maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider potential spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. Notably, this cartridge is not ideal for load-holding applications due to spool leakage. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for systems utilizing phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The design incorporates Sun's floating style construction to reduce internal part binding caused by excessive installation torque or machining variations. The RVEAMVN fits into a T-2A cavity and operates with a capacity of up to 30 gpm (120 L/min). It supports a maximum operating pressure of 5000 psi (350 bar) and has a control pilot flow ranging from 10-15 in\u00b3/min (0,16-0,25 L/min). Typical response time is around 10 ms with maximum valve leakage at specified conditions being 3 in\u00b3/min (50 cc/min). Adjustment requires up to five clockwise turns, with specific torque settings needed for installation and locknut adjustments. The model weighs approximately .70 lb (.30 kg) and comes with an optional Viton seal kit (990202006) for additional compatibility needs.
