The Sun Hydraulics RSJCCBN (RSJCCBN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This sequence valve regulates pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. It can substitute for 2-port relief valves when there's pressure in the return line. The RSJCCBN features interchangeable parts with other three-port sequence cartridges of the same frame size, allowing for consistent flow paths and cavity compatibility. The main stage orifice is protected by a robust 150-micron stainless steel screen, ensuring durability and reliability. The valve's pressure at port 3 directly adds to the valve setting at a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). It's important to note that this model isn't suitable for load-holding applications due to spool leakage. The RSJCCBN offers adjustable settings using W or Y controls, which can be specified with or without special settings. Without special settings, adjustments are possible throughout the full range; however, special settings indicate the maximum adjustable setting. Constructed with Sun's floating style design, this sequence valve minimizes internal part binding risks due to excessive installation torque or machining variations. It features a T-19A cavity and Series-4 capacity with a flow rate of up to 120 gpm (480 L/min). The factory pressure settings are established at 4 gpm (15 L/min), and it operates under a maximum pressure of 5000 psi (350 bar). With control pilot flows between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response times around 10 ms, this model offers efficient performance for various hydraulic applications.
