The Sun Hydraulics RSDSKWN (RSDSKWN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. It features a design that makes it insensitive to back pressure at port 2 up to the valve's set point, allowing it to regulate pressure effectively in place of two-port relief valves when there is pressure in the return line. This model is part of the 3-port sequence cartridges, which are interchangeable in terms of flow path and cavity size for a given frame size. The valve includes a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures at port 3 up to 5000 psi (350 bar), which directly adds to the valve setting at a 1:1 ratio. It is suitable for load-holding applications and cross-port relief circuits due to its ability to accept maximum pressure at port 2. The RSDSKWN incorporates Sun's floating style construction, minimizing internal part binding from excessive installation torque or machining variations. The cartridge has a capacity of 15 gpm (60 L/min), with factory pressure settings established at 4 gpm (15 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with a typical response time of 10 ms and minimal leakage upon reseat. Installation requires specific torque settings: valve installation torque between 30-35 lbf\u00b7ft (41-47 Nm), and locknut torque between 80-90 lbf\u00b7in (9-10 Nm). This model weighs approximately .30 lb (.15 kg) and uses Viton seal kits for optimal performance and durability.
