The Sun Hydraulics DNDCXHV924N (Material Number: DNDCXHV924N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic flow control. It is spring-centered to a neutral position and provides versatile flow paths based on coil activation. When coil A is energized, the valve directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B reroutes flow from port 3 to port 4 and from port 2 to port 1. This valve features a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve operates without requiring minimum hydraulic pressure due to its direct actuation design. It is particularly beneficial in differential flow circuits where higher return flows should be managed through specific ports for optimal performance. The cartridge's EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based substances as they can cause damage. A notable feature of this valve is its wet armature design, which allows the working fluid to absorb heat generated by the coil\u2014a consideration for systems where prolonged energization occurs. The unique magnetic design of the solenoid enhances efficiency by providing substantial spool actuating force per watt expended, facilitating reliable operation. This model also offers flexibility with various coil termination and voltage options, including surge protection capabilities. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Additionally, it incorporates Sun's floating style construction to prevent internal binding due to installation or machining variations. With a capacity of handling up to 5 gpm (20 L/min) and a switching frequency of up to 15,000 cycles per hour, this valve suits demanding applications requiring robust performance and adaptability.
