The Sun Hydraulics RSBCKWN (RSBCKWN) 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 valve regulates pressure at port 1 in relation to the drain port 3 and is insensitive to back pressure at port 2 up to its set level, making it an alternative to 2-port relief valves when return line pressure is present. Featuring interchangeable cartridges with identical flow paths and cavities for a given frame size, this sequence valve ensures compatibility across different systems. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and it has a minimum setting of 75 psi (5 bar) across all spring ranges. The valve can handle pressures at port 3 up to a maximum of 5000 psi (350 bar), directly affecting the valve setting on a 1:1 ratio basis. However, it is unsuitable for load-holding applications due to spool leakage. The RSBCKWN model incorporates Sun's floating style construction, which minimizes internal part binding risks due to excessive installation torque or machining variations. It features EPDM seals compatible with phosphate ester fluids but vulnerable to petroleum-based substances. With a capacity of 7.5 gpm (30 L/min) and factory settings established at 4 gpm (15 L/min), this model offers a typical response time of 10 ms and maximum leakage of 2 in\u00b3/min (30 cc/min) at specific conditions. The adjustment mechanism allows for up to five clockwise turns for increased settings, while installation requires specific torque values for optimal performance. This robust design makes it suitable for various hydraulic applications requiring precise pressure control without compromising system integrity.

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.
