The Sun Hydraulics DNDCXHV4E24V (DNDCXHV4E24V) 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 fluid control within hydraulic systems, offering reliable operation without requiring minimum hydraulic pressure. Upon energizing coil A, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This model features a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil. Users should be cautious with fluids like water-glycol mixtures that may degrade at high temperatures over time. The valve accommodates various coil termination and voltage options, with or without surge protection, enhancing its adaptability in different settings. Its unique magnetic design results in a high-efficiency solenoid that delivers significant spool actuating force per watt expended. The DNDCXHV4E24V incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or cavity machining variations. It fits a T31A cavity and belongs to Series 1 with a capacity of up to 5 gpm (20 L/min). The valve's response time is typically around 50 ms, with a maximum leakage rate of approximately 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It can handle switching frequencies up to 15,000 cycles per hour. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional weatherized coils and kits are available for enhanced environmental protection, offering IP69K ratings on certain connector options for robust performance in demanding conditions.
