The Sun Hydraulics RVIDCBV (RVIDCBV) is a ventable, pilot-operated, balanced piston relief cartridge valve with an external drain, designed to function as a normally closed pressure regulating valve. When the inlet port 1 pressure reaches the pre-set level, it opens to tank port 2, throttling flow to maintain the desired 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. This valve is known for its accuracy, low-pressure rise versus flow, smooth operation, quiet performance, and moderate speed. The RVIDCBV can handle maximum pressure at port 2 and is suitable for use in 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. Pressure at port 4 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). Cartridges with EPDM seals are intended for systems with phosphate ester fluids; exposure to petroleum-based fluids will damage these seals. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. With a capacity of up to 120 gpm (480 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge features a response time of approximately 10 ms and maximum leakage of 5 in\u00b3/min at 110 SUS/24 cSt under certain conditions. Installation requires specific torque settings and adjustments are made via an internal hex adjustment screw. The model weight is approximately 3.10 lb (1.40 kg), and it includes a Viton seal kit option (990-024-006).
