The Sun Hydraulics RVGELWV (RVGELWV) is a fast-acting, ventable, pilot-operated, balanced piston relief cartridge designed for pressure regulation in hydraulic systems. This normally closed valve regulates pressure by opening to the tank port when the inlet pressure reaches a set threshold, allowing flow throttling. It features a vent port for remote control by other valves, making it versatile for various applications. The RVGELWV is suitable for cross-port relief circuits due to its ability to accept maximum pressure at port 2; however, spool leakage should be considered in such uses. Notably, it is not suitable for load-holding applications due to potential leakage. The valve incorporates Sun's floating style construction to reduce the risk of internal binding from installation torque or machining variations. Key specifications include a cavity type T-17A with a series 3 capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with a typical response time of 2 ms. Maximum valve leakage at 110 SUS (24 cSt) is specified at 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Adjustment settings can be increased through five clockwise turns, and installation requires specific torque values: valve installation torque is between 150 and 160 lbf ft (203 to 217 Nm), while locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). The valve's hex size is measured at 1\u00bc inches (31.8 mm), with an internal hex size for adjustment screws of ^5\u204432 inches (4 mm) and locknut hex size of ^9\u204416 inches (15 mm). The model weighs approximately 1.60 lb (0.70 kg) and includes a Viton seal kit cartridge option under part number: 990017006.
