The Sun Hydraulics RVGDCEN (RVGDCEN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain designed for pressure regulation. This valve is normally closed and opens to the tank port when the inlet pressure reaches the set level, effectively throttling flow to maintain the desired pressure. It features a vent port for remote control by other pilot or 2-way valves and a drain port that renders it insensitive to back pressure. Notably, this valve is accurate, exhibits low pressure rise versus flow, operates smoothly and quietly, and responds moderately fast. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. However, it's not suitable for load-holding applications due to potential spool leakage. The pressure at port 4 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). The valve incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or cavity/cartridge machining variations. This model fits into Cavity T-23A and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). It features a control pilot flow of 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time of around 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is rated at 4 in\u00b3/min under a differential of 1000 psi (65 cc/min under a differential of 70 bar). Installation specifications include various hex sizes and torque requirements for secure setup.
