The Sun Hydraulics DNDCXCE912N (DNDCXCE912N) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control. This valve is spring-centered to maintain a neutral position when not energized. When coil A is activated, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B allows flow from port 3 to port 4 and from port 2 to port 1. Engineered with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar), this valve performs reliably without requiring minimum hydraulic pressure for operation. The DNDCXCE912N is ideal for differential flow circuits where the higher return flow should be directed through ports designed for optimal performance. It features EPDM seals suitable for phosphate ester fluid systems but requires caution against exposure to petroleum-based substances that could compromise seal integrity. The wet armature design enhances durability but necessitates consideration of fluid breakdown at elevated temperatures during prolonged coil energization. Offering versatility, this model supports various coil termination and voltage configurations with optional surge protection. Its magnetic design ensures high efficiency by delivering substantial spool actuating force per watt consumed, leading to dependable valve shifts. Coils are interchangeable with other Series 1 solenoid products and can be mounted in either direction, accommodating diverse operational needs. With a capacity of handling up to 5 gpm (20 L/min) and a response time of approximately 50 ms, the DNDCXCE912N suits applications requiring frequent switching cycles\u2014up to 15,000 per hour. Additional features include IP69K-rated coil connector options and weatherized kits for enhanced environmental protection. The valve's floating style construction minimizes internal binding risks due to installation torque or machining variations, ensuring consistent performance across diverse applications.
