The Sun Hydraulics RSDSLNN (RSDSLNN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at 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 the valve setting. It offers an alternative to two-port relief valves when there is pressure in the return line. The RSDSLNN is compatible with all three-port sequence cartridges of the same frame size, ensuring physical and functional interchangeability. As the inlet pressure at port 1 surpasses the setting relative to drain port 3, pilot flow continues to increase. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. This valve can handle pressures at port 3 directly additive to its setting in a 1:1 ratio, not exceeding 5000 psi (350 bar). It's suitable for load holding applications and immune to cavitation-related issues like noise and manifold erosion due to internal modulation within the cartridge. The RSDSLNN can accept maximum pressure at port 2, making it suitable for cross-port relief circuits. Its floating style construction minimizes internal binding risks due to installation torque or machining variations. With a cavity type of T-11A Series 1 and a capacity of up to 15 gpm (60 L/min), this model has factory pressure settings established at 4 gpm (15 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). It boasts a typical response time of just 10 ms and minimal valve leakage upon reseat. The adjustment requires approximately five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments.

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.
