The Sun Hydraulics RVGDKAN (RVGDKAN) is a ventable, pilot-operated, balanced piston relief cartridge that functions as a normally closed pressure regulating valve. This advanced hydraulic component is designed to open to tank port 2 when the pressure at inlet port 1 reaches the preset valve setting, thereby throttling flow to maintain regulated pressure. It features a vent port (port 3) for remote control by other pilot or two-way valves and an external drain port (port 4) that ensures insensitivity to back pressure. The RVGDKAN is known for its accuracy, low-pressure rise versus flow characteristics, smooth operation, and moderate speed. This relief cartridge is capable of accepting maximum pressure at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The main stage orifice of the valve is protected by a 150-micron stainless steel screen. It is not recommended for load-holding applications due to potential spool leakage. The valve setting can be directly influenced by the pressure at port 4 at a ratio of 1:1, with a maximum allowable pressure of 5000 psi (350 bar). The RVGDKAN incorporates Sun's floating style construction which minimizes the risk of internal parts binding from excessive installation torque or cavity/cartridge machining variations. It can handle up to 60 gpm (240 L/min) capacity and operates under a maximum pressure of 5000 psi (350 bar). The response time typically measures around 10 ms with maximum valve leakage at specified conditions being approximately 4 in\u00b3/min (65 cc/min). Adjustments can be made with up to five clockwise turns using an internal hex size of 5/32 inches, while installation requires a torque range between 150-160 lbf ft (203-217 Nm). The model weighs approximately 1.60 lb (0.70 kg), and it comes with Viton seals as part of its cartridge seal kit.
