The Sun Hydraulics RSJSLQN (RSJSLQN) is a pilot-operated, balanced poppet sequence valve designed to manage flow to a secondary circuit once the inlet port pressure exceeds the valve setting. This model controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2, up to the valve setting. It can regulate pressure in place of two-port relief valves when there is return line pressure. The RSJSLQN is interchangeable with all three-port sequence cartridges of the same frame size, offering versatility in application. The valve's main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability under high-pressure conditions up to 5000 psi (350 bar). Its design incorporates Sun's floating style construction, minimizing issues related to internal part binding due to installation torque or machining variations. With a capacity of 120 gpm (480 L/min) and factory pressure settings established at 4 gpm (15 L/min), this model exhibits typical response times of 2 ms and maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). Installation requires specific torque settings for both the valve and locknut, ensuring secure placement and operation. The RSJSLQN also features an internal hex adjustment screw for setting adjustments with five clockwise turns needed to increase settings. This robust component weighs approximately 3.10 lb (1.40 kg) and includes a Viton seal kit for maintenance needs, making it suitable for high-demand hydraulic applications where precise sequencing is essential.
