The Sun Hydraulics DNDAXNN712N (DNDAXNN712N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar), ensuring robust performance in demanding applications. It operates without the need for minimum hydraulic pressure and offers several manual override options, although these are not compatible with weatherized coils. The valve's manual control assembly has a mechanical life expectancy of approximately 7,000 cycles when equipped with the D or L control. It's important to note that cartridges with EPDM seals are intended for systems using phosphate ester fluids and can be damaged by petroleum-based substances. The valve features a wet armature design, which means the working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration is crucial as it can impact fluids like water-glycol mixtures over time due to potential varnish formation. The solenoid\u2019s innovative magnetic design enhances efficiency by maximizing spool actuating force per watt, ensuring reliable shifting of the valve. Coils are interchangeable within Sun Series 1 solenoids and can be mounted in either direction, offering flexibility in installation. Additional specifications include a cavity size of T-31A, a series designation of 1, and a capacity of 10 gpm (40 L/min). The maximum operating pressure stands at 5000 psi (350 bar), with typical response times around 50 ms and maximum leakage rates at specified conditions being minimal. With a switching frequency capability of up to 15,000 cycles per hour and various coil termination options available\u2014including those rated up to IP69K\u2014this cartridge valve is versatile for diverse applications requiring precise directional control 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.
