The Sun Hydraulics RSDSLQN (RSDSLQN) 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 control the pressure at port 1 in relation to the pressure at drain port 3, and it remains unaffected by back pressure at port 2 up to the valve setting. It can serve as a substitute for 2-port relief valves when there's pressure in the return line. All three-port sequence cartridges are interchangeable in terms of flow path and cavity size for a given frame size. As the pressure at port 1 relative to port 3 increases beyond the valve setting, pilot flow continues to rise. The main stage orifice is protected by a durable 150-micron stainless steel screen, ensuring robust performance. The RSDSLQN is suitable for load-holding applications and can handle maximum pressures up to 5000 psi (350 bar). Its design minimizes issues related to cavitation, such as noise and manifold erosion, due to internal modulation within the cartridge. The valve accepts maximum pressure at port 2 and is appropriate for use in cross-port relief circuits. It features Sun's floating style construction, reducing risks of internal part binding from excessive installation torque or machining variations. The RSDSLQN operates with a cavity T-11A series 1 capacity of up to 15 gpm (60 L/min) and has a typical response time of about 10 ms. The maximum valve leakage at reseat is minimal, with just around 10 drops per minute (0.7 cc/min). Adjustments are made with clockwise turns, and specific torque settings are provided for installation and locknut adjustments. The model weighs .30 lb (0.15 kg) and uses Viton seal kits for enhanced durability.

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.
