The Sun Hydraulics RVGDCDV (RVGDCDV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed to function as a normally closed pressure regulating valve. When the pressure at the inlet port reaches the preset value, the valve opens to the tank port, effectively throttling flow and regulating pressure. This model features a vent port that allows for remote control by other pilot or two-way valves and a drain port that ensures insensitivity to back pressure. Known for its accuracy and smooth operation, this valve exhibits low pressure rise versus flow and operates quietly. It is capable of handling maximum pressures at port 2 and is suitable for use 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, though it is not recommended for load-holding applications due to potential spool leakage. The RVGDCDV incorporates Sun's floating style construction to minimize binding risks from installation torque or machining variations. It fits into a T-23A cavity and offers a capacity of 60 gpm (240 L/min). The factory establishes pressure settings at 4 gpm (15 L/min), with maximum operating pressures reaching up to 5000 psi (350 bar). Control pilot flow ranges between 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with typical response times around 10 ms. Valve leakage is minimal at specified conditions, with adjustments made via a clockwise turn mechanism consisting of five turns to increase settings. Installation requires specific torque values for both the valve body and locknut components. The model weighs approximately 1.60 lb (0.70 kg) and utilizes Viton seal kits for optimal performance in relevant applications such as cross-port relief circuits while ensuring reliability under demanding conditions.
