The Sun Hydraulics RSJSCCN (RSJSCCN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the valve setting. This valve effectively controls the pressure at port 1 relative to the drain port 3 and remains unaffected by back pressure at port 2, up to its set point. It can serve as an alternative to two-port relief valves in systems with pressure in the return line. Notably, all three-port sequence cartridges are interchangeable, offering consistent flow paths and cavity compatibility for a given frame size. The RSJSCCN features a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures at port 3 up to 5000 psi (350 bar), directly adding to the valve setting at a 1:1 ratio. This design helps prevent common cavitation issues such as noise and manifold erosion. The valve is suitable for cross-port relief circuits, accepting maximum pressure at port 2, and incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. With a capacity of 120 gpm (480 L/min) and factory pressure settings established at 4 gpm (15 L/min), this model operates under a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min), with a typical response time of approximately 2 ms. The RSJSCCN features minimal leakage rates upon reseat\u201410 drops/min (0.7 cc/min)\u2014and allows for adjustment via clockwise turns up to five-and-a-half times for increased settings. The installation torque ranges between 350-375 lbf\u00b7ft (474-508 Nm), ensuring secure integration into hydraulic systems.
