The Sun Hydraulics RVGDCBV (RVGDCBV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed as a normally closed pressure regulating valve. This valve opens to the tank port when the inlet pressure reaches a predetermined setting, effectively throttling flow to maintain pressure regulation. It features a vent port for remote control by other pilot or 2-way valves and an external drain port to minimize sensitivity to back pressure. The RVGDCBV is noted for its accuracy and low-pressure rise versus flow, ensuring smooth and quiet operation with moderate response speed. This model is capable of handling maximum pressures at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, but it is not recommended for load-holding applications due to potential spool leakage. Pressure at port 4 directly influences the valve setting on a 1:1 ratio and should not exceed 5000 psi (350 bar). The valve incorporates Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations. The RVGDCBV fits into Cavity T-23A Series 3 and has a capacity of up to 60 gpm (240 L/min). Factory pressure settings 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), and typical response time is around 10 ms. Maximum valve leakage under specific conditions is limited to 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Adjustment involves up to five clockwise turns for increased settings, with specific torque requirements for installation and locknut adjustments. The model weighs approximately 1.60 lb (0.70 kg) and utilizes Viton seal kits for optimal performance.
