The Sun Hydraulics RSBCLAN (RSBCLAN) is a pilot-operated, balanced piston sequence valve designed to regulate flow in secondary circuits once the pressure at the inlet port exceeds a predetermined setting. This valve is specifically engineered to control the pressure at port 1 relative to the drain port 3, while remaining unaffected by back pressure at port 2 up to its set point. It can be used as an alternative to two-port relief valves when there is pressure in the return line. The RSBCLAN model features interchangeable three-port sequence cartridges, ensuring compatibility in terms of flow path and cavity size for a given frame. The valve's main stage orifice is protected by a 150-micron stainless steel screen, and it has a minimum setting of 75 psi (5 bar) across all spring ranges. The maximum operating pressure for this model is 5000 psi (350 bar), with a response time typically around 10 milliseconds. It should be noted that this valve is not suitable for load holding applications due to spool leakage. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. With a capacity of 7.5 gpm (30 L/min) and factory settings established at 4 gpm (15 L/min), this sequence valve offers reliable performance in managing hydraulic pressures effectively within its specified parameters.
