The Sun Hydraulics RSJCYDV (RSJCYDV) is a high-performance pilot-operated, balanced piston sequence valve designed to manage secondary circuit flow once the inlet pressure at port 1 surpasses the valve setting. This valve effectively controls pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its set point. It offers a viable alternative to two-port relief valves when there is return line pressure. The RSJCYDV model ensures compatibility and interchangeability with all three-port sequence cartridges of similar frame size, maintaining consistent flow paths and cavity dimensions. This sequence valve features a main stage orifice protected by a robust 150-micron stainless steel screen. It can handle pressures at port 3 that directly add to the valve setting in a 1:1 ratio, withstanding pressures up to 5000 psi (350 bar). While not suitable for load-holding applications due to spool leakage, the valve provides adjustable settings via W or Y controls, which can be specified with or without special settings. Without special settings, adjustments span the full range; with them, they define the maximum setting. The RSJCYDV incorporates Sun's floating style construction, minimizing risks of internal part binding from excessive installation torque or machining variations. Its specifications include a T-19A cavity series with a capacity of 120 gpm (480 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), and typical response time is around 10 milliseconds. Maximum valve leakage measures at five in\u00b3/min under specific conditions. The model weighs approximately 3.10 lb (1.40 kg) and comes with an optional Viton seal kit for enhanced performance and durability.
