The Sun Hydraulics RVGDLWV (RVGDLWV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precision pressure regulation with an external drain. This normally closed valve opens to the tank port 2 when the inlet port 1 pressure reaches the set level, effectively throttling flow to maintain desired pressure levels. It features a vent port 3 for remote control and a drain port 4 that ensures insensitivity to back pressure. The valve is known for its accuracy, low pressure rise versus flow, smooth operation, quiet performance, and moderate response speed. It is capable of handling maximum pressures at port 2 and can be utilized in cross-port relief circuits, although users should account for spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. This valve is not suitable for load-holding applications due to potential spool leakage. Pressure at port 4 directly affects the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). The Sun floating style construction minimizes risks of internal binding from excessive installation torque or machining variations. The RVGDLWV fits into Cavity T-23A with Series 3 capacity of up to 60 gpm (240 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It has a control pilot flow rate of 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time of approximately 10 ms. Valve installation requires specific torques: hex size is 1-1/4 inches (31.8 mm), with installation torque between 150-160 lbf-ft (203-217 Nm). Additionally, the adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), requiring torque between 80-90 lbf-in (9-10 Nm). The model weighs approximately 1.60 lb (0.70 kg) and uses Viton seal kits for optimal performance.
