The Sun Hydraulics RVEAQBV (RVEAQBV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to tank port 2 when inlet pressure reaches the set point, effectively throttling flow to maintain desired pressure levels. It features a vent port, allowing remote control via other pilot or 2-way valves. The RVEAQBV is noted for its accuracy, low pressure rise versus flow, smooth operation, and moderate speed. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. Key specifications include a main stage orifice protected by a 150-micron stainless steel screen and an unsuitability for load-holding applications due to spool leakage. Backpressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for phosphate ester fluid systems; exposure to petroleum-based fluids can damage these seals. The valve employs Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. The RVEAQBV fits into Cavity T-2A and belongs to Series 2 with a capacity of up to 30 gpm (120 L/min). Its maximum operating pressure reaches 5000 psi (350 bar), with control pilot flow between 10-15 in\u00b3/min (0.16-0.25 L/min) and typical response time of about 10 ms. Maximum valve leakage at specified conditions is approximately 3 in\u00b3/min (50 cc/min). The adjustment mechanism involves five clockwise turns to increase settings, with specific torque requirements for installation and adjustment components provided for precision assembly and operation.
