The Sun Hydraulics RSJSKCN (RSJSKCN) is a high-performance pilot-operated, balanced poppet sequence valve designed to manage secondary circuit flow once the pressure at inlet port 1 surpasses the preset valve threshold. This component is adept at controlling pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve's set limit. It serves as a viable alternative to two-port relief valves in scenarios where return line pressure is present. Notably, all three-port sequence cartridges are interchangeable both physically and functionally within the same frame size, maintaining consistent flow paths and cavity dimensions. The valve's pilot flow escalates as the inlet pressure at port 1 increases relative to the drain pressure at port 3, beyond the valve setting. It features a main stage orifice shielded by a durable 150-micron stainless steel screen and supports a maximum operating pressure of 5000 psi (350 bar). The modulating action occurs internally within the cartridge, rendering it resistant to cavitation-related issues such as noise and manifold erosion. Additionally, this valve can handle maximum pressures at port 2, making it suitable for cross-port relief circuits. Its construction incorporates Sun's floating style design to reduce risks of internal binding due to installation torque or machining discrepancies. With a capacity of 120 gpm (480 L/min) and response time of approximately 2 ms, this model ensures efficient performance with minimal leakage upon reseat. It includes an adjustment feature with five clockwise turns for setting increases and requires specific installation torques for optimal operation. The RSJSKCN model has a weight of 3.10 lb (1.40 kg) and comes with Viton seal kits for enhanced durability and compatibility with hydraulic systems.
