The Sun Hydraulics DMDATNN212 (DMDATNN212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust industrial applications requiring precise control of hydraulic flow. The valve operates with a maximum capacity of 12 gpm (45 L/min) and can handle pressures up to 5000 psi (350 bar). It features a fast response time of typically 50 ms, ensuring quick and efficient operation. Key to its reliable performance is the incorporation of Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. The solenoid tube assembly of this model is fatigue rated for high-pressure service, enhancing its durability and lifespan under rigorous conditions. Additionally, the valve includes interchangeable coils from Sun Series 1 solenoid products, which can be mounted in either direction for flexible installation options. Designed with a wet armature setup, the DMDATNN212 allows the working fluid to surround the armature. While this design aids in cooling, it requires careful consideration of fluid selection as some fluids may degrade at higher temperatures. Notably, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it could damage the seals. This model also features manual override capabilities with a detent mechanism intended for temporary actuation only. The mechanical life expectancy for models equipped with D or L control in the manual override is approximately 7,000 cycles. This makes the DMDATNN212 an excellent choice for applications where manual intervention is occasionally necessary but not routinely required. Overall, the Sun Hydraulics DMDATNN212 offers a combination of flexibility, high-capacity performance, and durability suitable for various demanding hydraulic applications where precision and reliability are paramount.

This solenoid-operated 3-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.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 configured 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
