The Sun Hydraulics RSDSKAV (RSDSKAV) 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. This sequence valve controls the 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 if there is pressure in the return line. All three-port sequence cartridges are interchangeable, offering consistent flow paths and cavity dimensions for a given frame size. As inlet pressure at port 1 rises above the valve setting, pilot flow increases accordingly. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. The valve can handle a maximum operating pressure of 5000 psi (350 bar) and features a factory-set response time of approximately 10 milliseconds with minimal leakage upon reseat. It is suitable for load-holding applications and cross-port relief circuits due to its capacity to accept maximum pressure at port 2. The design incorporates Sun's floating style construction, minimizing risks of internal binding from excessive installation torque or machining variations. The RSDSKAV has a cavity T-11A, Series 1 capacity of 15 gpm (60 L/min), and requires an installation torque between 30-35 lbf ft (41-47 Nm). Its compact build includes a locknut hex size of 9/16 inch (15 mm) with a locknut torque specification of 80-90 lbf in (9-10 Nm). The model weighs .30 lb (.15 kg) and utilizes Viton seal kits for optimal performance in diverse applications.
