The Sun Hydraulics DNDATEV912 (DNDATEV912) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is robustly engineered with a solenoid tube assembly that is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring high performance and durability in demanding applications. The valve requires no minimum hydraulic pressure for operation, making it versatile for various systems. It offers multiple manual override options, although weatherized coils are not compatible with these overrides. Notably, models with D or L control feature a detent mechanism for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The DNDATEV912 utilizes a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. This feature can impact fluids like water-glycol mixtures during prolonged coil energization due to potential breakdown and varnish formation. The valve supports a wide range of coil termination and voltage options, some equipped with surge protection, enhancing its adaptability to different electrical configurations. Its high-efficiency solenoid design ensures reliable valve shifting by providing significant spool actuating force per watt expended. The cartridge is constructed using Sun's floating style to reduce risks of internal binding from excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into T31A cavities and belongs to Series 1, offering a capacity of 10 gpm (40 L/min). With a typical response time of 50 ms and maximum leakage at 110 SUS of 10 in\u00b3/min (3000 psi), this valve is suitable for high-frequency switching up to 15,000 cycles/hour. Its compact design features a solenoid tube diameter of .75 inches and requires an installation torque between 30-35 lbf ft (41-47 Nm). Seal kits are available in Viton material for both cartridge and coil applications.

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.
