The Sun Hydraulics RVGSLQN (RVGSLQN) is a ventable, pilot-operated, balanced-poppet relief cartridge designed to function as a normally closed pressure regulating valve. Upon reaching the valve setting at the inlet port 1, it begins to open toward tank port 2, modulating flow to maintain desired pressure levels. This model features a vent port 3 for remote control via other pilot or two-way valves, making it suitable for load-holding applications with zero-leak venting. The RVGSLQN demonstrates accuracy with low pressure rise relative to flow and operates smoothly and quietly at moderate speeds. Its design ensures immunity to cavitation-related issues such as noise and manifold erosion. This cartridge is well-suited for systems requiring EPDM seals compatible with phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. It can handle maximum pressure at port 2, making it ideal for cross-port relief circuits. The valve's setting can be controlled below its own threshold using a remote pilot relief on port 3 vent. Notably insensitive to fluctuations in oil temperature and contamination, this model incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The RVGSLQN accepts a cavity T-17A series 3 with a capacity of 50 gpm (200 L/min) and operates at pressures up to 5000 psi (350 bar). It maintains control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) with typical response times around 2 ms. Maximum valve leakage upon reseat is limited to 10 drops/min (0.7 cc/min). The valve features an adjustment mechanism that requires five clockwise turns to increase settings, supported by specifications including a valve hex size of 1\u00bc in (31.8 mm) and installation torque between 150-160 lbf ft (203-217 Nm).
