The Sun Hydraulics RSDSCWN (RSDSCWN) 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 model is particularly effective for load holding applications and can replace 2-port relief valves when there's pressure in the return line. It features a design that is insensitive to back pressure at port 2, up to the valve setting, and allows for interchangeable use with other 3-port sequence cartridges of the same frame size. The RSDSCWN incorporates Sun's floating style construction, which minimizes internal binding due to excessive installation torque or cavity machining variations. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability in various applications. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 15 gpm (60 L/min). The valve's response time is typically around 10 ms, with maximum leakage at reseat being only 10 drops/min (0.7 cc/min). The adjustment mechanism allows for up to five full clockwise turns to increase the setting, providing flexibility in pressure control. This model's cavity size is T-11A Series 1, and it requires an installation torque of 30-35 lbf ft (41-47 Nm), while the locknut torque specification is between 80-90 lbf in (9-10 Nm). With its robust design and reliable performance characteristics, the Sun Hydraulics RSDSCWN sequence valve offers dependable operation across various hydraulic systems.
