The Sun Hydraulics RSJSKAV (RSJSKAV) 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 sequence valve controls the pressure at port 1 relative to the drain port 3 while remaining insensitive to back pressure at port 2, up to the valve setting. It can regulate pressure in place of two-port relief valves if there is pressure in the return line. All three-port sequence cartridges are interchangeable with identical flow paths and cavity sizes for a given frame size. As the pressure at port 1 increases relative to port 3, pilot flow continues to rise above the valve setting. The main stage orifice features a protective 150-micron stainless steel screen. Pressure at port 3 directly adds to the valve setting in a 1:1 ratio and should not exceed 5000 psi (350 bar). These valves are resistant to cavitation-related issues like noise and manifold erosion due to internal modulation within the cartridge. The RSJSKAV accepts maximum pressure at port 2, making it suitable for cross-port relief circuits and employs Sun's floating style construction to minimize binding from excessive installation torque or machining variations. It fits into Cavity T-19A, Series 4, with a capacity of up to 120 gpm (480 L/min) and operates under pressures up to 5000 psi (350 bar). The control pilot flow is between 15-20 in\u00b3/min (0.25-0.33 L/min), and it has an approximate response time of 2 ms with maximum leakage at reseat being about ten drops/min (0.7 cc/min). The adjustment requires approximately five turns clockwise for increased settings, with specific torque requirements for installation and adjustment components provided for optimal performance and reliability.
