The Sun Hydraulics RSBCCWN (RSBCCWN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. The sequence valve's pressure setting regulates the pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. This feature allows it to regulate pressure in lieu of 2-port relief valves when there is return line pressure. The RSBCCWN model offers functional and physical interchangeability across all 3-port sequence cartridges, ensuring consistency in flow path and cavity size for a given frame. As inlet pressure at port 1 rises above the valve setting relative to drain port 3, pilot flow increases accordingly. The main stage orifice is safeguarded by a 150-micron stainless steel screen, with minimum settings starting at 75 psi for all spring ranges. Pressure at port 3 adds directly to the valve setting on a one-to-one basis and should not exceed 5000 psi. The RSBCCWN is unsuitable for load-holding applications due to spool leakage and should be used with EPDM seals in systems containing phosphate ester fluids, avoiding petroleum-based substances that may damage seals. It incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. With a capacity of 7.5 gpm and maximum operating pressure of up to 5000 psi, this model delivers typical response times of around 10 ms and minimal leakage rates under specified conditions. Installation requires specific torque settings for both the valve and locknut components, ensuring optimal performance and reliability in hydraulic systems.

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.
