The Sun Hydraulics DNDCXTE299 (DNDCXTE299) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed to be spring-centered to a neutral position. This versatile valve operates efficiently within hydraulic systems, offering precise directional control of fluid flow. 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. The solenoid tube assembly is engineered for high durability with a fatigue rating suitable for up to 5000 psi (350 bar) service pressure. This valve does not require a minimum hydraulic pressure for operation, making it adaptable for various applications. It is particularly effective in differential flow circuits where the higher return flow should be routed through port 2 A to port 1 T. The cartridge's EPDM seals are compatible with systems using phosphate ester fluids but are susceptible to damage if exposed to petroleum-based fluids or lubricants. Employing a wet armature design, the valve allows working fluid exposure around the armature which helps dissipate heat generated by the coil\u2014an important consideration for long-term coil energization scenarios. Its high-efficiency solenoid design ensures reliable shifting with significant spool actuation force per watt expended. The product offers flexibility with numerous coil termination and voltage options, some featuring surge protection. Coils can interchange with other Sun Series 1 solenoid products and mount in either direction on the tube. Coil connector options provide protection ratings up to IP69K, and additional weatherized kits are available for enhanced environmental resilience. With features like Sun's floating style construction minimizing internal part binding due to installation torque or cavity machining variations, this valve promises robust performance across demanding operational 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.
