The Sun Hydraulics RVGAMBN (Material Number: RVGAMBN) is a ventable, pilot-operated, balanced piston relief cartridge valve designed for precise pressure regulation. This valve remains normally closed until the inlet port pressure reaches its set threshold, at which point it opens to the tank port to manage flow and maintain consistent pressure levels. Featuring a vent port for remote control by other pilot or 2-way valves, this model is known for its accuracy, smooth operation, and moderate response speed. It can withstand maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should be mindful of spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. Note that this valve is not appropriate for load-holding applications due to potential spool leakage. The back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for systems using phosphate ester fluids only; exposure to petroleum-based substances can damage these seals. The Sun floating style construction minimizes the risk of internal components binding from excessive installation torque or machining variations. With a cavity size of T-17A and series 3 capacity up to 60 gpm (240 L/min), this valve operates at a maximum pressure of 5000 psi (350 bar). It has a typical response time of 10 ms and minimal leakage rates under specified conditions. The adjustment involves up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustments detailed in its specifications.
