The Sun Hydraulics DMDATNN914N (DMDATNN914N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve offers closed transitions between its two positions\u2014spools B and R\u2014enhancing performance by ensuring faster and more consistent response times, particularly when used as pilot controls where capacity is less critical. The DMDATNN914N operates without the need for minimum hydraulic pressure, facilitating reliable performance across a range of conditions. It includes options for manual override through D, L, or T control assemblies; however, these are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Notably, this model is compatible with EPDM seals configured for phosphate ester fluids; caution is advised as exposure to petroleum-based fluids can damage these seals. Incorporating a wet armature design, the valve's working fluid surrounds the armature which may be exposed to heat if the coil remains energized over extended periods. This could lead to breakdowns in certain fluids like water-glycol mixtures. Additionally, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of the DMDATNN914N utilizes Sun's floating style to minimize internal part binding due to excessive installation torque or variations in cavity/cartridge machining. With specifications including a flow capacity of up to 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is engineered to meet rigorous industrial requirements while maintaining precise control and reliability in hydraulic systems.

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.
