The Sun Hydraulics DNDCXTVHN24AB (DNDCXTVHN24AB) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-performance hydraulic systems. This valve is spring-centered to the neutral position and offers distinct flow paths depending on which coil is energized. When coil A is activated, the flow moves from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs the flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is rated for fatigue at a service pressure of up to 5000 psi (350 bar), ensuring durability in demanding applications. This valve does not require a minimum hydraulic pressure for operation due to its direct actuated design. It incorporates Sun's floating style construction, minimizing the risk of internal component binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. The DNDCXTVHN24AB utilizes a wet armature design, where the working fluid surrounds the armature and can be affected by heat generated during prolonged coil activation. This feature necessitates caution with certain fluids that may degrade under such conditions. The valve supports various coil termination and voltage options, including configurations with surge protection for enhanced reliability. Coils are interchangeable with other Sun Series 1 solenoid products, allowing flexibility in installation direction on the tube. Coil connector options are available with ratings up to IP69K for robust environmental protection. With a capacity of handling flows up to 5 gpm (20 L/min) and featuring a rapid typical response time of approximately 50 ms, this spool valve is built for efficiency and reliability in high-cycle applications, supporting switching frequencies up to 15,000 cycles per hour. The DNDCXTVHN24AB also includes Viton seal kits compatible with phosphate ester fluids while being sensitive to petroleum-based substances.

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.
