The Sun Hydraulics RVGAKAV (RVGAKAV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve is typically closed and begins to open when the inlet port pressure reaches the preset level, directing flow to the tank port to manage pressure effectively. It features a vent port that allows remote control by other pilot or two-way valves, enhancing its versatility in various applications. The valve is known for its accuracy, smooth operation, low noise levels, and moderate response speed. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should account for potential spool leakage in such setups. The main stage orifice is protected by a 150-micron stainless steel screen for durability. This cartridge is not recommended for load-holding applications due to spool leakage concerns. Back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based substances as this could damage the seals. The Sun floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations. Key specifications include a cavity type of T-17A and series 3 capacity of up to 60 gpm (240 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 - 0.33 L/min), with typical response times around 10 ms. Maximum valve leakage at specified conditions is about 4 in\u00b3/min (65 cc/min). Installation requires specific torque settings and adjustments; the valve hex size is 1\u00bc inches (31.8 mm), and it weighs approximately 1.60 lbs (0.70 kg).
