The Sun Hydraulics RSBCCAN (RSBCCAN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This sequence valve controls 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 be used as a substitute for two-port relief valves in systems with return line pressure. The valve features interchangeable three-port sequence cartridges that maintain consistent flow paths and cavity sizes across given frame sizes. As inlet pressure at port 1 rises above the valve setting, pilot flow increases, protected by a 150-micron stainless steel screen. The minimum pressure setting for all spring ranges is 75 psi (5 bar), with maximum operating pressures reaching 5000 psi (350 bar). It is not suitable for load-holding applications due to spool leakage. Cartridges with EPDM seals are compatible only with phosphate ester fluids; exposure to petroleum-based fluids will damage these seals. The Sun floating style construction minimizes internal binding risks from excessive installation torque or machining variations. The RSBCCAN has a capacity of 7.5 gpm (30 L/min) and typical response time of 10 ms, with maximum leakage of 2 in\u00b3/min (30 cc/min) at specific viscosities. Adjustments are made via an internal hex screw and locknut, with specific torque settings provided for installation and adjustment components. The model weighs approximately .30 lb (0.15 kg), and its cavity size is T-163A Series 0, offering reliable performance in hydraulic applications requiring precise sequencing control under varying pressures.
