The Sun Hydraulics DNDCXWV724 (DNDCXWV724) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic control. This valve is spring-centered to maintain a neutral position when not energized. Energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The valve is fatigue rated for service up to 5000 psi (350 bar) and requires no minimum hydraulic pressure for operation, making it suitable for various hydraulic systems. In applications involving differential flow circuits, it is recommended that higher return flows are directed through port 2 A to port 1 T. The valve's EPDM seals are compatible with phosphate ester fluids but should be avoided in systems using petroleum-based fluids. Featuring a wet armature design, the valve's operational fluid surrounds the armature and helps dissipate heat generated by the coil; however, prolonged energization can lead to fluid breakdown in certain mixtures. The DNDCXWV724 offers versatility with various coil termination and voltage options available, including configurations with surge protection. The solenoid's magnetic design ensures high efficiency with substantial spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection. This valve incorporates Sun's floating style construction, reducing the likelihood of internal part binding due to excessive installation torque or machining variations. It fits into cavity T-31A and has a capacity of up to 5 gpm (20 L/min). With a typical response time of about 50 ms and a switching frequency of up to 15,000 cycles per hour, the DNDCXWV724 delivers reliable performance in demanding applications.
