The Sun Hydraulics RVGDKEN (RVGDKEN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed to function as a normally closed pressure regulating valve. This model is engineered to open to tank port 2 when the inlet port 1 pressure reaches the preset valve setting, effectively throttling flow to maintain regulated pressure. It features a vent port 3 for remote control by other pilot or two-way valves and a drain port 4 that ensures insensitivity to back pressure. The RVGDKEN is known for its accuracy, smooth and quiet operation, low-pressure rise versus flow characteristics, and moderate speed. This relief cartridge can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. It's important to note that this model is not recommended for load-holding applications due to potential spool leakage. The main stage orifice protection includes a 150-micron stainless steel screen. Additionally, the pressure at port 4 directly adds to the valve setting at a 1:1 ratio with a maximum of 5000 psi (350 bar). The Sun floating style construction minimizes internal binding risks due to excessive installation torque or cavity/cartridge machining variations. The RVGDKEN has a cavity T-23A series with a capacity of up to 60 gpm (240 L/min), operates at pressures up to 5000 psi (350 bar), and has a typical response time of about 10 ms. Its maximum valve leakage rate is specified as four in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Installation requires specific torques: valve installation torque between 150-160 lbf ft (203-217 Nm), adjustment screw internal hex size of ^5/32 in (4 mm), locknut hex size ^9/16 in (15 mm), and locknut torque between 80-90 lbf in (9-10 Nm). The model weight stands at approximately 1.60 lb (0.70 kg) with Viton seal kit option available under part number 990023006.
