The Sun Hydraulics RVGAKKV (Material Number: RVGAKKV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches a set threshold, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control through other pilot or 2-way valves, offering enhanced versatility. Known for its accuracy and smooth operation, the RVGAKKV provides low pressure rise versus flow and operates quietly with moderate speed. The valve can accept maximum pressure at port 2, making it suitable for 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 to ensure durability and performance. Notably, this cartridge is not suitable for load-holding applications due to potential spool leakage. The back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio, which must be accounted for during installation and operation. Cartridges with EPDM seals are compatible with phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. Constructed with Sun's floating style design, this valve minimizes internal binding risks due to installation torque or machining variations. It fits into Cavity T-17A and offers a series 3 capacity of up to 60 gpm (240 L/min). The factory-set pressures are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response times around 10 milliseconds and maximum valve leakage at specified conditions being minimal. The model weighs approximately 1.60 lbs (0.70 kg) and requires specific installation torques for optimal performance.
