The Sun Hydraulics DNDATXN848 (DNDATXN848) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable performance in high-pressure applications. Its direct actuation requires no minimum hydraulic pressure for operation, making it versatile across various systems. The cartridge offers multiple manual override options; however, note that manual overrides are incompatible with weatherized coils. Models with D or L control have a detent mechanism intended for temporary actuation and boast a mechanical life expectancy of approximately 7,000 cycles. This valve is equipped with EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design allows the working fluid to cool the armature and coil but may lead to varnish formation in certain fluids like water-glycol mixtures over time if the coil is energized continuously. The DNDATXN848 provides various coil termination and voltage options, including surge protection capabilities. Its unique magnetic design enhances solenoid efficiency by delivering high spool actuating force per watt expended, ensuring consistent valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Additional features include coil connector options rated up to IP69K for enhanced environmental protection and floating style construction to minimize internal part binding due to installation torque or machining variations. This cartridge fits into T31A cavities and handles flow capacities up to 10 gpm (40 L/min) with a maximum operating pressure of 5000 psi (350 bar). It exhibits typical response times of around 50 ms and has a switching frequency of up to 15,000 cycles per hour.

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.
