The Sun Hydraulics DNDCXYV814N (DNDCXYV814N) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise fluid control applications. This valve features a spring-centered mechanism that returns it to the neutral position when not energized. Upon energizing coil A, the flow is directed 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 robustly constructed for fatigue resistance up to a maximum operating pressure of 5000 psi (350 bar), ensuring reliable performance in demanding conditions. This valve operates without requiring any minimum hydraulic pressure, making it highly versatile for various hydraulic systems. It incorporates a wet armature design where the working fluid surrounds the armature, which may influence performance if exposed to continuous high temperatures; certain fluids like water-glycol mixtures can degrade over time under such conditions. The valve supports a range of coil termination and voltage options, with some configurations offering surge protection. The unique magnetic design of the solenoid enhances efficiency by providing high spool actuating force per watt expended. This results in dependable valve shifting capabilities. The interchangeable coils can be mounted in either direction and are compatible with other Sun Series 1 solenoid products. For enhanced environmental protection, weatherized coils and kits are also available. The DNDCXYV814N utilizes Sun's floating style construction to minimize internal binding due to installation torque or machining variations in cavity/cartridge interfaces. It fits into a T-31A cavity and has a capacity of up to 5 gpm (20 L/min), with a typical response time of approximately 50 ms and leakage rates at specified viscosity levels kept minimal at high pressures.

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.
