The Sun Hydraulics RSHSCWN (RSHSCWN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This valve effectively controls the pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its set point. It can replace 2-port relief valves when there's pressure in the return line and is suitable for load-holding applications. The RSHSCWN features a robust construction with interchangeable three-port sequence cartridges, ensuring compatibility across similar frame sizes. As pressure increases at port 1 compared to port 3, pilot flow also rises above the valve setting. The main stage orifice is safeguarded by a durable 150-micron stainless steel screen, and pressures at port 3 add directly to the valve setting on a one-to-one ratio, withstanding up to 5000 psi (350 bar). The internal modulating action of this cartridge minimizes issues like noise and manifold erosion caused by cavitation. Additionally, it accommodates maximum pressure at port 2 and is ideal for cross-port relief circuits. The design incorporates Sun's floating style construction, reducing risks of internal parts binding due to installation torque or machining variations. With a capacity of up to 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model provides reliable performance in demanding hydraulic systems. Key specifications include an adjustment range requiring five clockwise turns for increased settings, response time typically around 10 ms, and minimal leakage upon reseat. The valve's hex size measures 1-1/4 inches (31.8 mm), with an installation torque requirement of between 150-160 lbf-ft (203-217 Nm).

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.
