The Sun Hydraulics RSJCYEN (RSJCYEN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure surpasses the valve's set threshold. This valve regulates pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its set point. It can substitute for 2-port relief valves when there's pressure in the return line, offering versatility in various hydraulic applications. The RSJCYEN features interchangeable 3-port sequence cartridges, allowing for consistent flow paths and cavity compatibility across different frame sizes. The pilot flow increases as the inlet pressure at port 1 rises above the valve setting relative to port 3. The main orifice is safeguarded by a durable 150-micron stainless steel screen. Pressure at port 3 directly adds to the valve setting at a ratio of 1:1, with a maximum allowable pressure of 5000 psi (350 bar). It's important to note that this model is not suitable for load-holding applications due to potential spool leakage. The RSJCYEN incorporates Sun's floating style construction, which minimizes internal binding risks from excessive installation torque or machining variations. The factory settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating capacity of up to 120 gpm (480 L/min). The control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min), and it exhibits a typical response time of about 10 milliseconds. Additional specifications include an adjustment range facilitated by W or Y controls, with clockwise turns increasing settings up to five turns. Installation requires specific torque values for both the valve and locknut components, ensuring secure and efficient operation within hydraulic systems.
