The Sun Hydraulics RSJSKCV (RSJSKCV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the pre-set valve pressure. This valve controls the pressure at port 1 in relation to the drain port 3 and remains unaffected by back pressure at port 2 up to its set point. It can replace 2-port relief valves in systems where there's return line pressure. All three-port sequence cartridges from Sun are interchangeable, offering consistent flow paths and cavity requirements for a given frame size. The valve's pilot flow increases as the inlet pressure at port 1 rises above the valve setting relative to port 3. A protective feature includes a 150-micron stainless steel screen safeguarding the main stage orifice. The maximum allowable pressure at port 3 is additive to the valve setting on a one-to-one basis and should not exceed 5000 psi (350 bar). The internal modulating design makes this valve resistant to cavitation issues like noise and manifold erosion, making it suitable for cross-port relief circuits. It features Sun's floating style construction, minimizing potential internal part binding due to excessive installation torque or machining variations of cavity/cartridge interfaces. The RSJSKCV has a T-19A cavity series with a capacity of 120 gpm (480 L/min) and operates under a maximum pressure of 5000 psi (350 bar). Its control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response times around 2 milliseconds. Valve leakage is minimal at reseat, measuring approximately ten drops per minute (0.7 cc/min). Adjustment requires five clockwise turns for increased settings, with specific torque values provided for installation and locknut adjustments. The model weighs approximately 3.10 lb (1.40 kg) and uses Viton seal kits (990219006).
