The Sun Hydraulics DNDATDV628 (DNDATDV628) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered for high reliability with a fatigue-rated solenoid tube assembly capable of 5000 psi (350 bar) service. It operates without requiring a minimum hydraulic pressure and offers various manual override options, though models with weatherized coils are incompatible with manual overrides. The D, L, and T manual controls have a mechanical life expectancy of about 7,000 cycles and require specific force for actuation. The valve is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. Featuring a wet armature design, the valve's working fluid surrounds the armature, which can be affected by heat if the coil is energized for extended periods\u2014particularly important for water-glycol mixtures that may form varnishes over time. The DNDATDV628 boasts high efficiency due to its unique magnetic design, providing substantial spool actuating force per watt. It supports various coil termination and voltage configurations with options for surge protection. Coils are interchangeable within the Sun Series 1 range and can be mounted in either direction. The valve also incorporates Sun's floating style construction to reduce internal binding risk from excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), it has a typical response time of 50 ms and leakage rate at maximum conditions of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The compact design features a solenoid tube diameter of .75 inches (19 mm) and requires an installation torque between 30 to 35 lbf ft (41 to 47 Nm).

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
