The Sun Hydraulics RVEACCV (RVEACCV) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. This model is engineered to open to tank port 2 when the inlet port 1 pressure reaches the valve setting, thereby throttling flow to regulate pressure. It features a vent port 3 for remote control by other pilot or two-way valves. The RVEACCV is noted for its accuracy, low pressure rise versus flow, smooth and quiet operation, and moderate speed. It can accept maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen. It is not recommended for load-holding applications due to spool leakage concerns. The 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 using phosphate ester fluids and are not compatible with petroleum-based fluids. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. Additional specifications include a cavity T-2A Series 2 capacity of 30 gpm (120 L/min), a factory pressure setting established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 10\u201315 in\u00b3/min (0.16\u20130.25 L/min) with a typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is specified as 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). The adjustment mechanism includes five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments detailed in the product's technical specifications.
