The Sun Hydraulics DNDATLN912 (DNDATLN912) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate without requiring a minimum hydraulic pressure, making it versatile for various applications. It features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring robust performance in demanding environments. The valve includes multiple manual override options, although these are not compatible with weatherized coils. The manual control assembly offers approximately 7,000 cycles of mechanical life expectancy when equipped with the D or L control detent mechanism. This cartridge utilizes a wet armature design, allowing the working fluid to surround the armature and manage heat generated by the coil. However, users should be cautious of fluid breakdown at elevated temperatures over time, particularly with water-glycol mixtures. A wide range of coil termination and voltage options are available to meet specific requirements, including configurations with surge protection. The high-efficiency solenoid design provides significant spool actuating force per watt expended, ensuring reliable valve shifting. The DNDATLN912 incorporates Sun's floating style construction to prevent internal parts from binding due to excessive installation torque or cavity-cartridge machining variations. It fits into a T-31A cavity and has a capacity of 10 gpm (40 L/min) with maximum operating pressure up to 5000 psi (350 bar). Typical response time is around 50 ms with minimal leakage at specified conditions. This model supports a switching frequency of up to 15,000 cycles per hour and requires specific manual override force and stroke parameters for operation. The valve has an installation torque range of 30 - 35 lbf ft (41 - 47 Nm) and weighs approximately .60 lb (.30 kg).

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.
