The Sun Hydraulics RSJCLWV (RSJCLWV) 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's setting. This valve controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to the valve setting, making it suitable for regulating pressure in place of 2-port relief valves when there is return line pressure. The RSJCLWV features interchangeable 3-port sequence cartridges that share the same flow path and cavity for a given frame size, with pilot flow increasing as inlet pressure rises above the valve setting. It includes a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures up to 5000 psi (350 bar). However, it is not suitable for load holding applications due to spool leakage. The valve incorporates Sun's floating style construction, minimizing binding from excessive installation torque or machining variations. With a capacity of 120 gpm (480 L/min), its factory pressure settings are established at 4 gpm (15 L/min). It has a maximum operating pressure of 5000 psi (350 bar) and control pilot flow between 15\u201320 in\u00b3/min (0.25\u20130.33 L/min). The typical response time is around 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is approximately 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). Adjustments can be made with up to five clockwise turns to increase settings, requiring specific torque values for installation and locknut adjustments. This model weighs approximately 3.10 lb (1.40 kg) and utilizes Viton seals for enhanced durability.
