The Sun Hydraulics DNDCXCE514 (DNDCXCE514) is a highly efficient direct acting, solenoid-operated, 4-way, 3-position spool valve. It is engineered to be spring-centered to a neutral position and offers precise fluid control through its unique design. When coil A is energized, the flow transitions 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. This valve is fatigue rated for service up to 5000 psi (350 bar), ensuring reliable performance under high-pressure conditions. A key feature of this valve is its direct actuation mechanism that eliminates the need for minimum hydraulic pressure for operation. Its robust design makes it suitable for differential flow circuits by directing higher return flows efficiently. The DNDCXCE514 incorporates EPDM seals compatible with phosphate ester fluids but requires caution against petroleum-based substances which could damage the seals. The valve's wet armature design allows working fluid exposure around the armature, which can affect function if exposed to heat over prolonged periods. This consideration is crucial when using fluids like water-glycol mixtures prone to breakdown at elevated temperatures. The solenoid\u2019s magnetic design enhances efficiency by providing high spool actuating force per Watt expended, ensuring reliable shifting. Customization options include a variety of coil terminations and voltage configurations, some offering surge protection and environmental ratings up to IP69K. Coils are interchangeable with other Sun Series 1 products, enhancing versatility in application setups. The DNDCXCE514 features Sun's floating style construction that minimizes internal binding risks due to installation torque or machining variations, making it an ideal choice for stable and robust hydraulic systems requiring fast switching capabilities up to a frequency of 15,000 cycles per hour.
