The Sun Hydraulics RSJSLCN (RSJSLCN) 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 controls the pressure at port 1 relative to the drain port 3 pressure, and it remains insensitive to back pressure at port 2 up to the valve setting. It can replace two-port relief valves when there's return line pressure. All three-port sequence cartridges are interchangeable, providing consistent flow paths and cavity compatibility for a given frame size. As the inlet pressure at port 1 rises above the set point relative to drain port 3, pilot flow increases. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and performance. The RSJSLCN model features Sun's floating style construction, minimizing internal part binding due to excessive torque or machining variations. It accommodates maximum pressure at port 2 and is suitable for cross-port relief circuits. The valve has a capacity of up to 120 gpm (480 L/min) and operates under a maximum pressure of 5000 psi (350 bar). It has a control pilot flow ranging between 15-20 in\u00b3/min (0.25-0.33 L/min), with a typical response time of about 2 milliseconds. Valve leakage upon reseat is minimal, capped at 10 drops/min (0.7 cc/min). Adjustments are made via an internal hex screw, with five full clockwise turns needed to increase settings. The RSJSLCN model weighs approximately 3.10 lb (1.40 kg) and comes with specific torque requirements for installation and adjustment components, ensuring precise operation in demanding applications where reliable sequencing is crucial for system performance and safety.

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).
- 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.
