The Sun Hydraulics RVGDLAV (Material Number: RVGDLAV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain designed for precise pressure regulation. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the preset level, effectively throttling flow to maintain consistent pressure. It features a vent port 3 for remote control via other pilot or two-way valves and a drain port 4 that ensures insensitivity to back pressure. Known for its accuracy and low-pressure rise versus flow, this valve operates smoothly and quietly with moderate speed. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen. It's not recommended for load-holding applications due to potential spool leakage. The pressure at port 4 directly adds to the valve setting at a 1:1 ratio but should not exceed 5000 psi (350 bar). The Sun floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. This model fits cavity T-23A and Series 3, with a capacity of up to 60 gpm (240 L/min) and maximum operating pressure of 5000 psi (350 bar). It has a control pilot flow between 15 - 20 in\u00b3/min (0.25 - 0.33 L/min) and typical response time of approximately 10 ms. Maximum valve leakage is rated at four in\u00b3/min at 110 SUS (24 cSt) under pressures up to 1000 psi (70 bar). The adjustment requires approximately five clockwise turns to increase settings, with specific hex sizes and torque requirements detailed for installation and maintenance purposes. The model weighs approximately 1.60 lb (0.70 kg), with Viton seal kit available under part number: 990023006.
