The Sun Hydraulics RSJCKAV (RSJCKAV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow when the inlet port pressure exceeds the valve setting. This sequence valve effectively controls the pressure at port 1 relative to the drain port 3, remaining insensitive to back pressure at port 2 up to the valve's setting. It can be used as an alternative to 2-port relief valves when there is pressure in the return line. Notably, all 3-port sequence cartridges from this series are interchangeable, offering consistent flow paths and cavity compatibility for a given frame size. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the pressure at port 3 directly adds to the valve setting at a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). This model is not recommended for load-holding applications due to potential spool leakage. The RSJCKAV incorporates Sun's floating style construction, reducing risks of internal binding from excessive installation torque or cavity machining variations. It features an adjustable range using W or Y controls and can be specified with or without special settings. The valve has a capacity of 120 gpm (480 L/min) and operates under pressures up to 5000 psi (350 bar). It demonstrates a typical response time of around 10 ms and has maximum leakage rates of about 5 in\u00b3/min at specific conditions. Installation requires specific torque settings, with adjustment screw and locknut sizes detailed for precise application needs. The model weighs approximately 3.10 lb (1.40 kg) and uses Viton seal kits for maintenance purposes.
