The Sun Hydraulics DNDCXTV814 (DNDCXTV814) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency performance in hydraulic systems. This valve is spring-centered to a neutral position and offers two distinct flow paths depending on the coil that is energized: 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 directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve operates without the need for minimum hydraulic pressure, making it suitable for various applications. In differential flow circuits, it is recommended that higher return flows are directed through port 2 A to port 1 T. It features EPDM seals, which are compatible with phosphate ester fluids but can be damaged by petroleum-based fluids. The wet armature design allows the working fluid to surround the armature and absorb heat generated by the coil; however, certain fluids like water-glycol mixtures may degrade over time due to heat exposure. The DNDCXTV814 provides multiple coil termination and voltage options, with some configurations offering surge protection. Its efficient magnetic design results in high spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, various weatherized coils and kits are available for enhanced environmental protection. The valve's floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this versatile valve meets demanding operational requirements effectively.

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.
