The Sun Hydraulics RVEDKEN (Material Number: RVEDKEN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain. These valves are designed as normally closed pressure regulating devices that open to the tank port when the inlet port pressure reaches the valve setting, thereby throttling flow to regulate pressure. The RVEDKEN model includes a vent port for remote control and a drain port to ensure insensitivity to back pressure. It is capable of accepting maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, but it is not suitable for load-holding applications due to spool leakage. Pressure at the drain port should not exceed 5000 psi (350 bar) and directly adds to the valve setting at a 1:1 ratio. This model incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or cavity/cartridge machining variations. The valve has a capacity of 30 gpm (120 L/min) with factory pressure settings established at 4 gpm (15 L/min), and it operates up to a maximum of 5000 psi (350 bar). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), with a typical response time of 10 ms and maximum valve leakage at specified conditions being 3 in\u00b3/min (50 cc/min). The adjustment requires up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustments detailed in its specifications. This model weighs .70 lb (.30 kg) and can be configured with EPDM seals for systems using phosphate ester fluids, while exposure to petroleum-based fluids will damage these seals.
