The Sun Hydraulics RSFSCBN (RSFSCBN) is a pilot-operated, balanced poppet sequence valve designed to manage the flow to a secondary circuit once the pressure at inlet port 1 surpasses the valve setting. This valve is engineered to regulate pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can serve as a substitute for two-port relief valves when there is return line pressure. The RSFSCBN features interchangeable three-port sequence cartridges with identical flow paths and cavities for a given frame size, enhancing its versatility in various applications. The valve's pilot flow increases as inlet pressure at port 1 rises above the set point relative to drain port 3, while a 150-micron stainless steel screen safeguards the main stage orifice. The maximum allowable pressure at port 3 is directly additive to the valve setting with a limit of 5000 psi (350 bar), making it suitable for load-holding tasks and cross-port relief circuits. Thanks to its internal modulating design, this valve mitigates issues such as cavitation-related noise and manifold erosion. Constructed with Sun's floating style architecture, it minimizes potential binding of internal components due to excessive installation torque or machining variations in cavity/cartridge assembly. With specifications including a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and response time typically around 10 ms, this model ensures efficient performance. Additionally, it features adjustment capabilities via an internal hex screw and locknut with specified torque values, providing precise control over settings. The RSFSCBN also includes Viton seal compatibility through an optional cartridge seal kit (990402006).

Pilot-operated, balanced poppet 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.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Suitable for use in load holding applications.
- Because the modulating occurs inside the cartridge these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- 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.
