The Sun Hydraulics RSJSLQV (RSJSLQV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This valve effectively controls the pressure at port 1 relative to port 3, remaining insensitive to back pressure at port 2 up to the valve setting. It can be utilized as a substitute for two-port relief valves when there is pressure in the return line. The RSJSLQV model features full interchangeability with other three-port sequence cartridges, maintaining consistent flow paths and cavities for equivalent frame sizes. The pilot flow increases as the pressure differential between ports 1 and 3 surpasses the set value, with a main stage orifice protected by a 150-micron stainless steel screen. The RSJSLQV can handle maximum pressures of up to 5000 psi (350 bar) at port 3, directly adding to the valve setting in a 1:1 ratio. This construction makes it immune to common cavitation issues such as noise and manifold erosion. Additionally, it accepts maximum pressure at port 2, making it suitable for cross-port relief circuits. The Sun floating style construction minimizes potential binding of internal parts due to excessive installation torque or machining variations. With a capacity of up to 120 gpm (480 L/min) and factory pressure settings established at 4 gpm (15 L/min), this model offers reliable performance with control pilot flows between 15 - 20 in\u00b3/min (0.25 - 0.33 L/min). It has a typical response time of about 2 ms and minimal leakage at reseat of approximately 10 drops/min (0.7 cc/min). Installation requires specific torque settings for various components, ensuring secure and effective operation within its specified parameters.
