The Sun Hydraulics DNDCXYV514 (Material Number: DNDCXYV514) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic systems. This valve is spring-centered to a neutral position and can be actuated by energizing either coil A or B. When coil A is energized, the flow direction is from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly of this valve is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability in demanding applications. This valve requires no minimum hydraulic pressure for operation, making it versatile for various system requirements. For differential flow circuits, it is recommended that higher return flows be directed through port 2 A to port 1 T. The DNDCXYV514 incorporates a wet armature design where the working fluid surrounds the armature, which can influence performance if the coil is energized for extended periods due to heat exposure. A range of coil termination and voltage options are available, offering flexibility in configuration with or without surge protection. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 products and support IP69K-rated connector options for enhanced environmental protection. The valve features Sun's floating style construction, reducing internal binding risks due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min) and typical response times around 50 ms, this valve suits applications requiring rapid switching frequencies up to 15,000 cycles per hour. It incorporates Viton seal kits for both cartridge and coil components for reliable sealing performance in various fluid environments.

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.
