The Sun Hydraulics DNDCXTNHN24AB (DNDCXTNHN24AB) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic control applications. This valve is spring-centered to a neutral position and features dual coil operation: 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. It is fatigue-rated for service pressures up to 5000 psi (350 bar) and operates without the need for minimum hydraulic pressure. The valve's design incorporates a wet armature system, enhancing its reliability by allowing the working fluid to cool the solenoid coil, although care should be taken with fluids like water-glycol mixtures that may degrade over time at high temperatures. The DNDCXTNHN24AB offers high efficiency with its unique magnetic solenoid design that delivers significant spool actuating force per watt. It supports interchangeable coils with other Sun Series 1 products and provides various termination and voltage options, including IP69K-rated connectors for enhanced environmental protection. Built using Sun's floating style construction, it minimizes internal part binding risks due to installation torque or machining variations. The valve fits into T31A cavities with a capacity of up to 5 gpm (20 L/min) and features a rapid response time of approximately 50 milliseconds. It is engineered for high switching frequency operations of up to 15,000 cycles per hour and maintains minimal leakage under standard conditions. This robust valve solution is ideal for precise hydraulic control in dynamic systems requiring reliable performance under demanding conditions.

This direct acting, solenoid-operated, 4-way, 3-position spool valve is spring centered to the neutral position. When coil A is energized, the flow is from port 3 (P) to port 2 (A) and from port 4 (B) to port 1 (T). When coil B is energized, the flow is from port 3 to port 4 and from port 2 to port 1.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- In differential flow circuits, the higher return flow should be directed through port 2 (A) to port 1 (T).
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
