The Sun Hydraulics RSJCKEV (RSJCKEV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This sequence valve regulates pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. It can replace 2-port relief valves if there is return line pressure. All three-port sequence cartridges are interchangeable, offering consistent flow paths and cavity sizes across frame sizes. The valve features a main stage orifice protected by a 150-micron stainless steel screen and maintains a maximum operating pressure of 5000 psi (350 bar). It supports pilot flows of 15-20 in\u00b3/min (0.25-0.33 L/min) with typical response times of 10 ms. The maximum leakage at 110 SUS (24 cSt) is rated at 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). The RSJCKEV incorporates Sun's floating style construction to prevent internal binding due to excessive installation torque or machining variations, making it unsuitable for load-holding applications due to spool leakage. The valve's adjustment range can be modified using W or Y controls, with specific settings determining the maximum adjustment limit if specified. Installation requires a hex size of 1-5/8 inches (41.3 mm) and torque specifications between 350-375 lbf\u00b7ft (474-508 Nm). It weighs approximately 3.10 lb (1.40 kg) and utilizes Viton seal kits for cartridge sealing needs, ensuring robust performance across various hydraulic applications while maintaining precise control over system pressures.
