The Sun Hydraulics RSJCLAN (RSJCLAN) 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. It precisely controls the pressure at port 1 relative to the drain port 3 and remains unaffected by back pressure at port 2 up to the valve setting. This valve can substitute two-port relief valves when there's pressure in the return line. All three-port sequence cartridges are interchangeable, maintaining consistent flow paths and cavity sizes for specific frame sizes. The pilot flow increases as inlet pressure rises above the valve setting, with a main stage orifice protected by a 150-micron stainless steel screen. The maximum allowable pressure at port 3 directly adds to the valve setting at a 1:1 ratio, capped at 5000 psi (350 bar). However, this model is unsuitable for load-holding applications due to spool leakage. For control options labeled W and Y, users can specify settings with or without special adjustments; without special settings, adjustments are possible throughout its full range. The Sun floating style construction minimizes internal binding risks from excessive torque or machining variations. Key specifications include a T-19A cavity, Series 4 capacity of 120 gpm (480 L/min), factory pressure settings established at 4 gpm (15 L/min), and maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response time around 10 ms and maximum leakage at specified conditions of 5 in\u00b3/min under certain pressures. Installation requires specific torque values for both the valve and locknut components, ensuring secure placement within hydraulic systems.
