The Sun Hydraulics DNDCXTE228 (DNDCXTE228) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision control in hydraulic systems. This valve is spring-centered to the neutral position and allows for versatile flow configurations: 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 features a robust solenoid tube assembly rated for fatigue at pressures up to 5000 psi (350 bar), ensuring reliable performance in demanding applications. The valve requires no minimum hydraulic pressure for operation, making it suitable for various direct actuation scenarios. The DNDCXTE228 incorporates a wet armature design that immerses the armature in working fluid, which can be beneficial or detrimental depending on the fluid type and operating conditions. Specifically, fluids such as water-glycol mixtures may degrade over time due to heat exposure when the coil is energized for extended periods. The valve supports various coil termination and voltage options with optional surge protection, providing flexibility in system integration. With a capacity of 5 gpm (20 L/min) and a rapid response time of approximately 50 milliseconds, this valve is engineered for high efficiency and reliability. Its unique magnetic design enhances solenoid efficiency by maximizing spool actuating force per watt expended. The DNDCXTE228 also features interchangeable coils compatible with other Sun Series 1 solenoid products, offering ease of maintenance and adaptability. Additional attributes include IP69K-rated coil connector options for enhanced environmental protection and Sun's floating style construction that minimizes internal binding risks due to installation torque or machining variations. This product is ideal for use in differential flow circuits where higher return flows are directed through specific ports, ensuring optimal system performance.

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.
