The Sun Hydraulics RSDSCBN (RSDSCBN) is a pilot-operated, balanced poppet sequence valve designed to manage secondary circuit flow once the inlet port 1 pressure surpasses the valve setting. This valve precisely controls pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to its set point. It can substitute for two-port relief valves when there is return line pressure, and all three-port sequence cartridges are interchangeable in terms of flow path and cavity size. The RSDSCBN features a 150-micron stainless steel screen protecting the main stage orifice and can handle up to 5000 psi (350 bar) at port 3. It's suitable for load-holding applications and is resistant to cavitation-related issues such as noise and manifold erosion due to internal modulating. This valve can accept maximum pressure at port 2, making it ideal for cross-port relief circuits. Its floating style construction minimizes binding risks from excessive torque or machining variations. With a capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), and a typical response time of 10 ms, this valve ensures efficient performance. It has minimal leakage at reseat with only 10 drops/min (0.7 cc/min). The adjustment requires five clockwise turns to increase settings, with installation torque between 30-35 lbf-ft (41-47 Nm). The model weighs .30 lb (.15 kg) and uses a Viton seal kit with part number 990011006 for maintenance needs.
