The Sun Hydraulics DNDCXAV628 (DNDCXAV628) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision fluid control in hydraulic systems. This valve is spring-centered to the neutral position and operates by energizing either coil A or coil B. When coil A is activated, 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 the flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is robustly engineered for fatigue resistance up to a service pressure of 5000 psi (350 bar), ensuring high reliability under demanding conditions. This versatile valve requires no minimum hydraulic pressure for operation, making it suitable for diverse applications. In differential flow circuits, it is advisable to direct higher return flows through port 2 A to port 1 T. The DNDCXAV628 features a wet armature design that allows the working fluid to surround the armature, which can influence performance if the coil remains energized for extended periods; certain fluids may degrade at elevated temperatures. The valve accommodates various coil termination and voltage options, with surge protection available as needed. Its high-efficiency solenoid design provides substantial spool actuating force per watt consumed, promoting dependable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. The DNDCXAV628 incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations in cavity/cartridge interfaces. It supports a capacity of up to 5 gpm (20 L/min) with a typical response time of approximately 50 ms and can handle switching frequencies up to 15,000 cycles per hour. The maximum allowable leakage at standard viscosity levels is minimal at specified pressures, ensuring efficient operation.

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.
