The Sun Hydraulics DNDATLN628 (DNDATLN628) is a solenoid-operated, 4-way, 2-position cartridge valve specifically designed for direct-acting and balanced spool directional control. This valve is engineered to operate efficiently without requiring a minimum hydraulic pressure, thanks to its direct actuation design. It features a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The valve's wet armature design allows the working fluid to surround the armature, which can influence thermal management if the coil remains energized for extended periods. This characteristic is crucial when using fluids like water-glycol mixtures that may degrade at elevated temperatures. The DNDATLN628 offers several manual override options, although manual override functionality does not support weatherized coils. For models with D or L control, the detent mechanism in the manual override is intended for temporary activation and has an approximate mechanical life expectancy of 7,000 cycles. The cartridge accommodates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based substances. This high-efficiency solenoid valve boasts a unique magnetic design that maximizes spool actuating force per watt expended, promoting reliable shifting. It supports various coil termination and voltage configurations with optional surge protection and interchangeable coils compatible with other Sun Series 1 products. Coil connector options have ratings up to IP69K for enhanced environmental protection. The valve's construction incorporates Sun's floating style to minimize internal binding risks from excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and response time typically around 50 ms, this versatile component suits numerous hydraulic applications requiring precise flow control and reliability under high-pressure conditions.

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.
