The Sun Hydraulics RVEAMKV (RVEAMKV) is a ventable, pilot-operated, balanced piston relief cartridge valve designed to regulate pressure within hydraulic systems. This normally closed pressure regulating valve opens to tank port 2 when the inlet port 1 pressure reaches the set threshold, efficiently throttling flow to maintain the desired pressure. It features a vent port (port 3) for remote control via other pilot or two-way valves, ensuring accurate and smooth operation with low pressure rise versus flow. The valve is capable of handling maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and while this valve is not ideal for load-holding applications due to potential spool leakage, it excels in other scenarios where precise pressure control is needed. Backpressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but are vulnerable to damage from petroleum-based substances. Incorporating Sun's floating style construction minimizes internal part binding risks due to installation torque or machining variations. The RVEAMKV has a capacity of 30 gpm (120 L/min) and operates at pressures up to 5000 psi (350 bar). Its typical response time is around 10 ms, with maximum leakage of 3 in\u00b3/min at specified conditions. The valve features adjustable settings with up to five clockwise turns and requires specific torque values for installation and adjustment components. This model weighs approximately .70 lb (.30 kg) and utilizes Viton seal kits (990202006) for optimal performance in various hydraulic applications requiring reliable pressure regulation.
