The Sun Hydraulics DNDCXWV298 (DNDCXWV298) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This valve is designed for efficient hydraulic flow management in various applications. 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. With a fatigue rating for service up to 5000 psi (350 bar), this robust valve does not require a minimum hydraulic pressure for operation, making it versatile across different systems. The DNDCXWV298 features a wet armature design, which means that the working fluid surrounds the armature and absorbs heat generated by the coil\u2014an important consideration in long-term operations where certain fluids may degrade at elevated temperatures. The valve supports differential flow circuits by directing higher return flows through specific ports for optimal performance. Cartridges with EPDM seals are specifically designed for phosphate ester fluids and are not compatible with petroleum-based substances. This model offers several coil termination and voltage configurations, including options with surge protection, ensuring adaptability to various operational needs. The high-efficiency solenoid design provides reliable valve shifting with significant spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. Additionally, coil connector options provide ratings up to IP69K for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal part binding due to installation torque or machining variations within cavities or cartridges. With a capacity of up to 5 gpm (20 L/min) and quick response times of approximately 50 ms, this valve supports high-frequency switching operations up to 15,000 cycles per hour while maintaining minimal leakage rates under specified conditions.
