The Sun Hydraulics RSFSLNN (RSFSLNN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses 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 setting, making it suitable for load holding applications and cross-port relief circuits. The RSFSLNN is equipped with a main stage orifice protected by a 150-micron stainless steel screen and features Sun's floating style construction, which minimizes internal binding due to installation torque or machining variations. This valve can handle maximum pressures of up to 5000 psi (350 bar) and has a capacity of 30 gpm (120 L/min). It operates with a typical response time of 10 ms and exhibits minimal leakage at reseat, measured at 10 drops/min (0.7 cc/min). The design incorporates an adjustment mechanism allowing for five complete clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. The RSFSLNN's versatility is enhanced by its interchangeability among all three-port sequence cartridges of the same frame size, ensuring compatibility in various configurations. This product is particularly beneficial for applications where pressure modulation within the cartridge itself prevents issues such as cavitation-related noise and manifold erosion. Additionally, it accepts maximum pressure at port 2 and maintains stable operation even when there is pressure in the return line. With its robust construction and precise control capabilities, this sequence valve is an excellent choice for demanding hydraulic systems requiring reliable performance under high-pressure conditions.

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.
