The Sun Hydraulics RSJCKCV (RSJCKCV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the valve setting. This valve effectively manages pressure at port 1 relative to the drain port 3, remaining 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. All three-port sequence cartridges are interchangeable, sharing identical flow paths and cavity dimensions for a given frame size. The pilot flow increases as the inlet pressure at port 1 rises above the valve setting relative to port 3. The main stage orifice is shielded by a 150-micron stainless steel screen for enhanced protection. The RSJCKCV model features a maximum operating pressure of 5000 psi (350 bar), with pilot flow control ranging from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min) and typical response time of approximately 10 milliseconds. However, it is not suitable for load-holding applications due to spool leakage. Adjustment is facilitated by W and Y controls, allowing full-range adjustability unless specified otherwise for special settings. The valve incorporates Sun's floating style construction, reducing internal part binding risks from excessive installation torque or machining variations. Additional specifications include a capacity of 120 gpm (480 L/min), maximum valve leakage of up to five in\u00b3/min at 1000 psi (80 cc/min at 70 bar), and an installation torque range of 350-375 lbf ft (474-508 Nm). It comes with a factory-set pressure established at four gpm (15 L/min). The model weighs approximately 3.10 lb (1.40 kg) and includes an internal hex size adjustment screw measuring ^5/32 inches (4 mm).
