The Sun Hydraulics RVGACEN (Material Number: RVGACEN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when the inlet pressure reaches its set point, allowing throttled flow to maintain desired pressure levels. It features a vent port that facilitates remote control via other pilot or 2-way valves, making it versatile for various hydraulic applications. The valve is engineered for accuracy with minimal pressure rise against flow and operates smoothly and quietly with moderate speed. It can handle maximum pressure at port 2 and is 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 valve setting is directly influenced by back pressure on the tank port at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; these seals are incompatible with petroleum-based fluids. The Sun floating style construction minimizes risks of internal binding caused by excessive installation torque or machining variations. Key specifications include a capacity of 60 gpm (240 L/min), maximum operating pressure of 5000 psi (350 bar), control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min), and typical response time of 10 ms. The valve's maximum leakage at 110 SUS (24 cSt) is rated at 4 in\u00b3/min (65 cc/min) under 1000 psi (70 bar). Adjustment requires up to five full clockwise turns to increase settings, with specific torque requirements for installation and adjustments detailed in the product documentation.
