The Sun Hydraulics DNDCXWV628 (DNDCXWV628) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency fluid control. This valve is spring-centered to the neutral position, ensuring reliable operation without the need for minimum hydraulic pressure. When coil A is energized, fluid flows 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 is fatigue-rated for service up to a maximum operating pressure of 5000 psi (350 bar), making it suitable for demanding applications. It features a wet armature design that allows working fluid to surround the armature, which can affect performance if the coil is energized for extended periods. The DNDCXWV628 valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It offers a capacity of up to 5 gpm (20 L/min) and features a quick response time of approximately 50 ms with a switching frequency of up to 15,000 cycles per hour. The valve's maximum leakage rate at standard conditions is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended due to their resistance against petroleum-based fluids. This model provides versatility in its coil termination and voltage options, with interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connectors offer protection ratings up to IP69K for enhanced environmental resilience. The valve's compact design includes a solenoid tube diameter of .75 inches (19 mm) and 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, ensuring durability in various operational settings.

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.
