The Sun Hydraulics DNDATJN928 (DNDATJN928) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. It operates without the need for minimum hydraulic pressure and offers various manual override options, although these are not compatible with weatherized coils. The valve is constructed with EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based products should be avoided as it may damage the seals. This valve employs a wet armature design, where the working fluid surrounds the armature and is exposed to coil heat. This design consideration is important when using fluids like water-glycol mixtures that can degrade over time due to heat exposure. The high-efficiency solenoid provides significant spool actuating force per watt expended, ensuring reliable valve shifting. The DNDATJN928 also supports a wide array of coil termination and voltage configurations with optional surge protection. Incorporating Sun's floating style construction minimizes internal part binding due to excessive installation torque or cavity machining variations. The cartridge fits into cavity T31A and belongs to Series 1, boasting a capacity of 10 gpm (40 L/min). It has a typical response time of 50 ms and can handle up to 15,000 cycles per hour switching frequency. With interchangeable coils compatible with other Sun Series 1 products and IP69K-rated connector options available, this model is versatile for various applications requiring robust directional control solutions in hydraulic systems.

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.
