The Sun Hydraulics RVGAMEV (Material Number: RVGAMEV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 once the inlet port 1 pressure reaches the preset level, effectively throttling flow to maintain desired pressure. It features a vent port 3 for remote control via other pilot or 2-way valves, offering smooth operation with low pressure rise versus flow. The valve is equipped with a stainless steel screen to protect the main stage orifice and can handle maximum pressure at port 2, making it suitable for cross-port relief circuits\u2014though spool leakage should be considered in such applications. This cartridge incorporates Sun's floating-style construction to minimize binding issues due to installation torque or machining variations. It is not recommended for load-holding applications due to potential spool leakage. The valve setting can be adjusted by turning the adjustment screw clockwise up to five times, with a locknut provided for secure positioning. The RVGAMEV model accepts back pressure on tank port 2 at a 1:1 ratio relative to the valve setting and comes standard with Viton seals; however, EPDM seals are available for systems using phosphate ester fluids\u2014these should not be exposed to petroleum-based fluids as they may cause damage. The cartridge fits into a T-17A cavity and has a series 3 capacity of up to 60 gpm (240 L/min), operating under pressures up to 5000 psi (350 bar). With typical response times of approximately 10 ms and control pilot flows between 15-20 in\u00b3/min (0.25-0.33 L/min), this valve ensures efficient performance in various hydraulic applications requiring controlled pressure relief and regulation.
