The Sun Hydraulics RSJCYEV (RSJCYEV) 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 effectively controls pressure at port 1 relative to the drain port 3 and remains insensitive to back pressure at port 2 up to the valve setting, making it suitable for replacing two-port relief valves when there's pressure in the return line. Notably, all three-port sequence cartridges are interchangeable within a given frame size, maintaining consistent flow paths and cavity dimensions. The RSJCYEV features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction to prevent internal binding due to excessive torque or machining variations. With a maximum operating pressure of 5000 psi (350 bar), this valve is not suitable for load-holding applications due to spool leakage. It offers adjustable settings through W or Y controls, with options for special settings representing maximum values. Key specifications include a capacity of 120 gpm (480 L/min), control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min), and typical response time of 10 ms. The valve installation requires torque between 350-375 lbf ft (474-508 Nm), while adjustment screw and locknut sizes are detailed with specific hex dimensions and torque requirements. Additionally, the model weight is approximately 3.10 lb (1.40 kg), and it utilizes Viton seals available in seal kit number 990019006. This sequence valve is engineered for precise pressure control applications where reliable performance under high-pressure conditions is essential, ensuring optimal functionality across various hydraulic systems while maintaining safety standards through robust design features.
