The Sun Hydraulics RVIDKCV (RVIDKCV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed to function as a normally closed pressure regulating valve. This component begins to open to the tank port when the inlet port pressure reaches the valve setting, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control by other pilot or two-way valves and a drain port that renders 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. This cartridge is suitable for cross-port relief circuits, accepting maximum pressure at port 2; however, spool leakage should be considered in such applications. It is not ideal for load-holding applications due to this leakage factor. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. The valve's adjustment settings can be fine-tuned through clockwise turns of an internal hex screw. The RVIDKCV operates at a maximum pressure of 5000 psi (350 bar) with a control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min). Its response time is typically around 10 milliseconds, and it has a maximum leakage rate of 5 in\u00b3/min at 110 SUS (24 cSt) under 1000 psi (70 bar). The cartridge incorporates Sun's floating style construction to minimize binding risks due to excessive installation torque or machining variations. Cartridges configured with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The RVIDKCV model weighs approximately 3.10 lb (1.40 kg) and requires specific installation torques for optimal performance.
