The Sun Hydraulics RVIAKCV (RVIAKCV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve begins to open at the inlet port when the pressure reaches its set point, allowing flow to throttle through to the tank port and regulate pressure. It features a vent port that enables remote control by other pilot or two-way valves. This valve is known for its accuracy, low pressure rise versus flow, smooth operation, quiet performance, and moderate response speed. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits with considerations for spool leakage. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring longevity and reliability. It's important to note that this valve is not suitable for load-holding applications due to potential spool leakage. The RVIAKCV incorporates Sun's floating style construction to minimize internal part binding caused by excessive installation torque or cavity/cartridge machining variations. Cartridges with EPDM seals are compatible with systems using phosphate ester fluids but should not be exposed to petroleum-based products as they can damage the seals. The valve has a capacity of 120 gpm (480 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The factory pressure settings are established at 4 gpm (15 L/min), with a control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). The typical response time is around 10 ms, with maximum leakage at 5 in\u00b3/min (1000 psi). Adjustment options include up to five clockwise turns to increase settings, ensuring flexibility in various applications where precise pressure control is essential.
