The Sun Hydraulics RSJCLWN (RSJCLWN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet pressure at port 1 surpasses the valve setting. This valve is particularly effective in controlling the pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can be utilized as a substitute for two-port relief valves when there is pressure in the return line. The RSJCLWN model offers interchangeable functionality and physical compatibility with all three-port sequence cartridges of similar frame size, ensuring ease of integration into various systems. Key features include a main stage orifice protected by a 150-micron stainless steel screen and an ability to handle pressures up to 5000 psi (350 bar) at port 3, which directly adds to the valve setting on a one-to-one ratio. However, it is not recommended for load-holding applications due to potential spool leakage. The valve incorporates Sun's floating style construction, reducing risks of internal part binding from excessive installation torque or machining variations. Additional specifications highlight its capacity of 120 gpm (480 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), with control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min). Typical response time stands at around 10 ms, and maximum valve leakage under specific conditions is rated at 5 in\u00b3/min (80 cc/min). Adjustments are made via an internal hex screw with specific torque requirements for both installation and locknut adjustments. The RSJCLWN model weighs approximately 3.10 lb (1.40 kg) and comes with Viton seal kit options for enhanced performance reliability.
