The Sun Hydraulics RSJCCDV (RSJCCDV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This sequence valve controls pressure at port 1 relative to the drain port 3, and it is 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. The RSJCCDV features interchangeable three-port sequence cartridges for consistent flow paths and cavity compatibility within a given frame size. It includes a 150-micron stainless steel screen to protect the main stage orifice and is not suitable for load-holding applications due to spool leakage. The valve can be adjusted throughout its full range using W or Y controls unless a special setting is specified, which represents its maximum setting. It incorporates Sun's floating style construction, minimizing internal parts binding from excessive installation torque or machining variations. The RSJCCDV fits into Cavity T-19A, Series 4, with a capacity of 120 gpm (480 L/min). Its maximum operating pressure reaches up to 5000 psi (350 bar), with control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time of 10 ms. Maximum valve leakage stands at five in\u00b3/min at 1000 psi (80 cc/min at 70 bar). Adjustments require up to five turns clockwise to increase settings, with specific dimensions for installation torque and hex sizes provided for precise fitting. The model weighs approximately 3.10 lbs (1.40 kg) and comes with available Viton seal kits for maintenance needs.
