The Sun Hydraulics RVEDLYV (RVEDLYV) is a ventable, pilot-operated, balanced piston relief cartridge valve with an external drain, designed to be a normally closed pressure regulating valve. This valve opens to tank port 2 when the inlet port 1 pressure reaches the set point, throttling flow to maintain regulated pressure. It features a vent port 3 for remote control by other pilot or two-way valves and a drain port 4 that makes it insensitive to back pressure. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. The RVEDLYV can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. It is not recommended for load-holding applications due to potential spool leakage. This cartridge includes a main stage orifice protected by a 150-micron stainless steel screen and can be configured with EPDM seals for use in systems with phosphate ester fluids\u2014note that exposure to petroleum-based fluids will damage these seals. The valve setting at port 4 is directly additive at a 1:1 ratio and should not exceed 5000 psi (350 bar). The design incorporates Sun's floating style construction to minimize potential binding from installation torque or machining variations. Specifications include a cavity type T-22A, series 2 capacity of up to 30 gpm (120 L/min), factory pressure settings established at 4 gpm (15 L/min), maximum operating pressure of 5000 psi (350 bar), control pilot flow of 10-15 in\u00b3/min (0.16-0.25 L/min), typical response time of approximately 10 ms, maximum valve leakage of up to 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar), adjustment via internal hex screw with specific torque requirements, and an overall weight of approximately .70 lb (.30 kg).
