The Sun Hydraulics DNDATHN712N (DNDATHN712N) is a solenoid-operated 4-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. Its solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), making it suitable for high-pressure applications. This valve operates without the need for minimum hydraulic pressure and offers multiple manual override options, though manual overrides are not compatible with weatherized coils. The manual override mechanism has a mechanical life of around 7,000 cycles when equipped with the D or L control. It features EPDM seals that are compatible with phosphate ester fluids but can be damaged by petroleum-based substances. The wet armature design allows the working fluid to cool the armature but may lead to varnish formation in certain fluids if the coil is energized for extended periods. The valve offers various coil termination and voltage configurations, some with surge protection, and its efficient magnetic design provides high spool actuating force per watt used. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction, while connector options offer protection ratings up to IP69K. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1, handling capacities of up to 10 gpm (40 L/min) at a maximum operating pressure of 5000 psi (350 bar). Typical response time is around 50 ms, with maximum leakage at specified conditions being 10 in\u00b3/min (160 cc/min). The switching frequency capability is 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.
