The Sun Hydraulics RSJCKAN (RSJCKAN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This valve is capable of controlling the pressure at port 1 relative to the pressure at drain port 3, and it remains unaffected by back pressure at port 2 up to the valve setting. It can serve as an alternative to 2-port relief valves when there is pressure in the return line. The RSJCKAN model features interchangeable 3-port sequence cartridges, allowing for consistent flow paths and cavity compatibility within a given frame size. As the inlet pressure rises above the valve setting, pilot flow increases accordingly. The main stage orifice is safeguarded by a stainless steel screen with a 150-micron rating. Pressure at port 3 adds directly to the valve setting at a 1:1 ratio but should not surpass 5000 psi (350 bar). Due to spool leakage, this model is unsuitable for load holding applications. The RSJCKAN incorporates Sun's floating style construction, minimizing potential internal binding from excessive installation torque or machining variations. It has a cavity size of T-19A and belongs to Series 4 with a capacity of up to 120 gpm (480 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min), and typical response time is around 10 ms. Maximum valve leakage is rated at 5 in\u00b3/min (80 cc/min) under specific conditions, and adjustments can be made via clockwise turns up to five times for increasing settings. The model weighs approximately 3.10 lb (1.40 kg) and includes specific installation torque requirements and adjustment details for optimal performance.
