While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics RSBCCQN (RSBCCQN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This sequence valve controls the pressure at port 1 relative to the pressure at drain port 3 and remains insensitive to back pressure at port 2 up to the valve setting. It can be used as an alternative to two-port relief valves when there is pressure in the return line. Its design allows for all three-port sequence cartridges to be physically and functionally interchangeable, maintaining consistent flow paths and cavity sizes for a given frame size. The pilot flow increases as the inlet pressure at port 1 rises above the valve setting relative to drain port 3. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and longevity. The minimum setting for this valve is 75 psi (5 bar) across all spring ranges, with maximum operating pressures reaching up to 5000 psi (350 bar). However, it is not suitable for load-holding applications due to spool leakage. Cartridges configured with EPDM seals are compatible with systems using phosphate ester fluids but should avoid exposure to petroleum-based fluids. The Sun Hydraulics floating style construction minimizes potential internal part binding due to excessive installation torque or machining variations. This model has a capacity of 7.5 gpm (30 L/min) and features a typical response time of approximately 10 milliseconds. With maximum valve leakage rated at 2 in\u00b3/min (30 cc/min), it provides reliable performance under various conditions. Installation torque ranges from 20-25 lbf ft (27-33 Nm), while adjustment settings require five clockwise turns for increased pressure settings, utilizing an internal hex size of 5/32 inches (4 mm).

Pilot-operated, balanced piston sequence valves will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3). These valves are insensitive to back pressure at port 2 (sequence), up to the valve setting. They may be used to regulate pressure in place of 2-port relief valves if there is pressure in the return line.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Pilot flow continues to increase as the pressure at port 1 (inlet), relative to the pressure at port 3 (drain), rises above the valve setting.
- The main stage orifice is protected by a 150 micron stainless steel screen.
- Minimum setting is 75 psi (5 bar) for all spring ranges.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Not suitable for use in load holding applications due to spool leakage.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
