The Sun Hydraulics RSJSCWN (RSJSCWN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This sequence valve effectively controls pressure at port 1 relative to the pressure at the drain port 3 and remains insensitive to back pressure at port 2 up to the valve setting. It can replace two-port relief valves in applications where there is return line pressure. All three-port sequence cartridges are interchangeable, providing flexibility in various applications. The valve features a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures at port 3 directly additive to the valve setting, up to a maximum of 5000 psi (350 bar). It is suitable for cross-port relief circuits, accepting maximum pressure at port 2. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. The RSJSCWN has a capacity of 120 gpm (480 L/min) and operates under a maximum pressure of 5000 psi (350 bar). Control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with a typical response time of 2 ms. Maximum valve leakage upon reseat is limited to 10 drops/min (0.7 cc/min). Adjustment parameters include five clockwise turns for increasing settings, with specific hex sizes for adjustments and locknuts, ensuring precise control and secure installation. The model weighs approximately 3.10 lb (1.40 kg) and includes Viton seals for enhanced durability in hydraulic systems.
