The Sun Hydraulics RSBCCNN (RSBCCNN) is a pilot-operated, balanced piston sequence valve designed to manage secondary circuit flow once the inlet port pressure surpasses the valve setting. This component precisely controls pressure at port 1 relative to port 3 and remains unaffected by back pressure at port 2, up to the valve setting. It can substitute for two-port relief valves when there is return line pressure. The RSBCCNN model showcases interchangeability across all three-port sequence cartridges, maintaining identical flow paths and cavity requirements within a specific frame size. Its main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. The valve's minimum setting is 75 psi (5 bar), with a maximum operating pressure of 5000 psi (350 bar). Pressure at port 3 directly adds to the valve setting at a 1:1 ratio but should not exceed the maximum limit. This model is not recommended for load-holding applications due to potential spool leakage. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; however, these seals are vulnerable to damage from petroleum-based substances. The RSBCCNN incorporates Sun's floating style construction, mitigating risks of internal binding caused by excessive installation torque or machining variations. It supports a capacity of 7.5 gpm (30 L/min) with factory settings established at 4 gpm (15 L/min). The response time typically measures around 10 ms, while maximum leakage is rated at 2 in\u00b3/min (30 cc/min) under specified conditions. Installation requires specific torques for various components: valve hex size at \u00be in., adjustment screw internal hex size at ^5/32 in., and locknut hex size at ^9/16 in., with corresponding torque values provided for optimal performance and security during setup.

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.
