The Sun Hydraulics DNDCXTEHN24AB (DNDCXTEHN24AB) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve allows for precise fluid control in hydraulic systems. It operates by energizing coil A to direct 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. The solenoid tube assembly is engineered for high fatigue resistance, rated for service up to 5000 psi (350 bar), ensuring durability under demanding conditions. This valve does not require a minimum hydraulic pressure for operation due to its direct actuation design. For differential flow circuits, it is recommended that higher return flows are directed through port 2 A to port 1 T. The valve features EPDM seals suitable for phosphate ester fluid systems; however, these seals are incompatible with petroleum-based fluids. Its wet armature design allows the working fluid to cool the armature but may lead to varnish formation in certain fluids when exposed to prolonged heat. The DNDCXTEHN24AB offers multiple coil termination and voltage options with surge protection capabilities, enhancing adaptability in various applications. The solenoid's efficient magnetic design provides high spool actuating force per watt expended, which ensures reliable valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Additional weatherized coils and kits are available for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min), a typical response time of 50 ms, and compatibility with cavity T-31A series installations, this valve is well-suited for robust hydraulic applications requiring reliable performance and adaptability.

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.
