The Sun Hydraulics DNDCXHV624 (DNDCXHV624) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision fluid control in hydraulic systems. This valve is spring-centered to maintain a neutral position when not energized. Activating 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 reroutes the flow from port 3 to port 4 and from port 2 to port 1. Engineered for robust performance, the solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The DNDCXHV624 operates without needing a minimum hydraulic pressure, which enhances its versatility in various systems. It is particularly effective in differential flow circuits where higher return flows should be directed through specific ports for optimal performance. Notably, this valve employs a wet armature design that allows the working fluid to surround the armature, which can be beneficial or detrimental depending on fluid type and operational duration due to potential heat exposure. This model offers a wide range of coil termination and voltage options with surge protection features available. The high-efficiency solenoid design ensures reliable valve shifting by providing substantial spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted bidirectionally on the tube. The valve's construction minimizes internal part binding due to installation or machining variations. With a capacity of up to 5 gpm (20 L/min) and a rapid response time of approximately 50 ms, this valve supports high-frequency switching up to 15,000 cycles per hour. It incorporates Viton seals compatible with phosphate ester fluids but caution should be taken when exposed to petroleum-based substances. This product also features environmental protection options with coil connectors rated up to IP69K for enhanced durability in harsh conditions.
