The Sun Hydraulics RVEAOTN (RVEAOTN) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. It opens to the tank port when the inlet pressure reaches the valve setting, effectively throttling flow to regulate pressure. This model features a vent port that allows for remote control by other pilot or 2-way valves, making it ideal for applications requiring precise pressure control. The valve is accurate and offers low pressure rise versus flow, ensuring smooth and quiet operation with moderate speed. A unique feature of this model is its ability to accept maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, although it's not suitable for load-holding applications due to potential spool leakage. This cartridge incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 30 gpm (120 L/min). The response time is typically around 10 milliseconds, with maximum valve leakage at 3 in\u00b3/min at 110 SUS (24 cSt). Adjustments can be made via an internal hex screw with five clockwise turns needed to increase the setting. It comes equipped with EPDM seals for use with phosphate ester fluids; exposure to petroleum-based substances will damage these seals. The RVEAOTN weighs approximately .70 lb (.30 kg), and its installation requires specific torque settings for optimal performance.
