The Sun Hydraulics DMDATNN211 (DMDATNN211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. Featuring a direct-acting, balanced spool design, this valve ensures efficient control with its ability to operate without minimum hydraulic pressure. It is particularly notable for its closed spool transitions between positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control systems where capacity is less critical. The DMDATNN211 is built to withstand demanding conditions, evidenced by its fatigue rating for up to 5000 psi (350 bar) service. This model incorporates a wet armature design allowing the working fluid to surround the armature which could be essential in applications where the coil may be energized for extended periods. However, it is crucial to consider the type of fluid used as some can degrade under heat, affecting performance. For versatility in maintenance and repair, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also utilizes Sun's floating style construction which helps minimize internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. Additionally, the DMDATNN211 offers a manual override feature with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The use of EPDM seals suggests suitability for systems utilizing phosphate ester fluids while cautioning against exposure to petroleum-based substances which could damage the seals. Overall, this valve's robust design and flexible operational features make it suitable for various hydraulic applications requiring reliable directional control and rapid response times.

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.
