The Sun Hydraulics DNDCXTE514 (DNDCXTE514) 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 features a robust solenoid tube assembly rated for 5000 psi (350 bar) service. It operates without requiring minimum hydraulic pressure, making it versatile for various applications. 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 directs flow from port 3 to port 4 and from port 2 to port 1. The valve's wet armature design allows working fluid exposure to coil-generated heat; however, caution is advised with fluids like water-glycol mixtures that may degrade over time. Compatible with EPDM seals for phosphate ester fluids, it avoids petroleum-based fluids due to potential seal damage. The DNDCXTE514 offers high efficiency through its unique magnetic solenoid design, ensuring reliable valve shifting with high spool actuating force per Watt expended. It supports a range of coil termination and voltage options, including interchangeable coils with other Sun Series 1 solenoid products. Coil connector options offer protection up to IP69K standards for enhanced durability. The valve's floating style construction minimizes binding risks due to installation torque or machining variations. Key specifications include a capacity of 5 gpm (20 L/min), typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and a switching frequency of up to 15,000 cycles per hour. The valve's hex size is .78 inches (22.2 mm), and it requires an installation torque between 30-35 lbf ft (41-47 Nm). Seal kits are available in Viton material for both cartridge and coil components.

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.
