The Sun Hydraulics DNDCXCE812N (DNDCXCE812N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for versatile hydraulic applications. This valve is spring-centered to the neutral position, ensuring reliable operation under various conditions. When coil A is energized, the flow directs from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for fatigue resistance up to a service pressure of 5000 psi (350 bar), making it suitable for high-pressure environments. This valve requires no minimum hydraulic pressure for operation due to its direct actuation design, which enhances its adaptability in different hydraulic circuits. For differential flow circuits, directing the higher return flow through port 2 A to port 1 T optimizes performance. It incorporates EPDM seals compatible with phosphate ester fluids but unsuitable for petroleum-based fluids, which can damage the seals. The DNDCXCE812N features a wet armature design where working fluid surrounds the armature and dissipates heat generated by the coil. This aspect is crucial if the coil remains energized for extended durations, as some fluids may degrade at high temperatures over time. The solenoid's magnetic design ensures high efficiency and reliable valve shifting with substantial spool actuating force per watt expended. With interchangeable coils compatible with other Sun Series 1 solenoid products and multiple coil termination options offering protection ratings up to IP69K, this valve provides flexibility in installation and environmental protection. Its floating style construction minimizes internal binding risks due to installation torque or machining variations. The DNDCXCE812N supports a capacity of up to 5 gpm (20 L/min) and demonstrates a typical response time of approximately 50 ms with minimal leakage under specified conditions.
