The Sun Hydraulics RSBCLCN (RSBCLCN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This versatile valve manages pressure at port 1 relative to port 3, remaining unaffected by back pressure at port 2 up to its setting. It can substitute for 2-port relief valves when there's return line pressure and features interchangeable design across all 3-port sequence cartridges with the same flow path and cavity size. The valve's main stage orifice is protected by a durable 150-micron stainless steel screen, and it offers a minimum setting of 75 psi (5 bar). Pressure at port 3 adds directly to the valve setting at a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). Not suitable for load-holding applications due to potential spool leakage, this model is compatible with phosphate ester fluids when configured with EPDM seals but should avoid petroleum-based substances. The floating style construction minimizes internal part binding risks from excessive torque or machining variations. With a capacity of 7.5 gpm (30 L/min) and factory settings established at 4 gpm (15 L/min), it operates under pressures up to 5000 psi (350 bar) and responds typically within 10 ms. Valve leakage at standard conditions is minimal, recorded at up to 2 in/min (30 cc/min). Adjustment requires five clockwise turns for increased settings, using an internal hex screw size of 5/32 in (4 mm), while installation torque ranges from 20\u201325 lbf ft (27\u201333 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits for maintenance.
