The Sun Hydraulics DNDCXTE212 (DNDCXTE212) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to a neutral position. This valve effectively controls hydraulic flow with precision and reliability. When coil A is energized, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. Designed for fatigue-rated service up to 5000 psi (350 bar), this valve requires no minimum hydraulic pressure for operation, making it highly versatile in various applications. The DNDCXTE212 features a wet armature design, which allows the working fluid to surround the armature and absorb heat generated by the coil. This can be crucial in applications where the coil remains energized for extended periods since certain fluids may degrade at high temperatures over time. The valve is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based substances. With a capacity of handling up to 5 gpm (20 L/min) and a typical response time of just 50 ms, this valve offers efficient performance with minimal leakage under maximum operating conditions. It incorporates Sun's floating style construction, reducing potential binding issues due to installation torque or machining variations. Additionally, the solenoid's magnetic design ensures high efficiency with significant spool actuating force per watt expended. The DNDCXTE212 provides various coil termination and voltage options with interchangeable coils compatible across Sun Series 1 solenoid products. Coil connector options offer protection ratings up to IP69K, enhancing durability in demanding environments. The seal kit for this cartridge includes Viton materials for robust sealing performance under diverse 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.
