The Sun Hydraulics DNDCXTN514 (DNDCXTN514) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic control. This valve is spring-centered to the neutral position and offers versatile flow configurations when coils are energized. Specifically, 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 channels flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for durability with a fatigue rating for service up to 5000 psi (350 bar). Notably, this valve requires no minimum hydraulic pressure for operation, making it ideal for applications where differential flow circuits are present. It features EPDM seals suitable for systems using phosphate ester fluids but cautions against exposure to petroleum-based substances. The DNDCXTN514 utilizes a wet armature design that immerses the armature in working fluid, potentially affecting performance if exposed to prolonged coil energization due to heat generation. This design consideration is crucial when using water-glycol mixtures that may degrade into varnishes over time. The high-efficiency solenoid design delivers robust spool actuating force per watt expended, ensuring reliable operation. Additionally, the valve supports various coil termination and voltage options, including surge protection features. Coil interchangeability with other Sun Series 1 solenoid products enhances versatility and ease of maintenance. The valve incorporates Sun's floating style construction to minimize internal part binding risks due to installation torque or machining variations within the cavity/cartridge interface. With a capacity of up to 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve is adept at handling demanding hydraulic applications with precision and reliability.

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.
