The Sun Hydraulics DNDCXTE298 (DNDCXTE298) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high efficiency and reliable performance. This valve features a spring-centered neutral position and operates without the need for minimum hydraulic pressure. It is suitable for applications requiring directional control of fluid flow, with specific configurations based on coil energization: energizing coil A allows flow from port 3 P to port 2 A and from port 4 B to port 1 T, while coil B facilitates flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability in demanding environments. The DNDCXTE298 incorporates a wet armature design, which allows the working fluid to surround the armature and potentially influence thermal conditions during prolonged coil activation. It is important to note that fluids such as water-glycol mixtures may degrade under these conditions over time. The valve supports a range of coil termination and voltage options, including those with surge protection, ensuring versatility in various applications. This model features a capacity of up to 5 gpm (20 L/min) and has a typical response time of approximately 50 ms, making it suitable for high-frequency switching operations up to 15,000 cycles per hour. The valve's construction minimizes internal binding risks due to installation torque or machining variations through Sun's floating style design. For optimal performance in systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended; however, these should not be exposed to petroleum-based substances. Additional environmental protection can be achieved through weatherized coils and kits available separately. The DNDCXTE298's interchangeable coils are compatible with other Sun Series 1 solenoid products, offering flexibility in installation orientation.

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.
