The Sun Hydraulics RVGAKGV (RVGAKGV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve is normally closed and activates when the inlet pressure at port 1 reaches the preset level, allowing flow to tank port 2 to manage the pressure effectively. It features a vent port 3 that facilitates remote control by other pilot or two-way valves, enhancing its versatility in various applications. Known for its accuracy and low-pressure rise relative to 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, although spool leakage should be considered in such configurations. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. However, it is not recommended for load holding applications due to potential spool leakage. The back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; however, these seals are not compatible with petroleum-based fluids. This cartridge incorporates Sun's floating style construction to minimize internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. It fits into a T-17A cavity of Series 3 with a capacity of up to 60 gpm (240 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with 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 1000 psi (65 cc/min at 70 bar). Installation requires specific torque values for optimal performance and longevity.
