The Sun Hydraulics RVIDCCV (RVIDCCV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed for precise pressure regulation. These normally closed pressure regulating valves open to tank port 2 when the inlet port 1 reaches the set pressure, effectively throttling flow to maintain desired pressure levels. The inclusion of a vent port (port 3) allows for remote control via other pilot or two-way valves, while a drain port (port 4) ensures insensitivity to back pressure. Notably accurate and smooth in operation, these valves exhibit low pressure rise against flow and moderate response speed. The RVIDCCV is capable of accepting maximum pressure at port 2 and can be used in cross port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. This model is not recommended for load-holding applications due to potential spool leakage. Pressure at port 4 directly adds to the valve setting at a 1:1 ratio with a maximum limit of 5000 psi (350 bar). Configured with EPDM seals, this cartridge is suitable for systems utilizing phosphate ester fluids but should avoid exposure to petroleum-based substances which could damage the seals. The design incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Additional specifications include a cavity size of T-24A and Series 4 capacity of up to 120 gpm (480 L/min). It operates under maximum pressures of 5000 psi (350 bar), with control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). With typical response times around 10 ms and minimal valve leakage at standard conditions, this model offers reliable performance across various hydraulic applications.
