The Sun Hydraulics DMDATNN228 (DMDATNN228) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. 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's transition between positions is closed with spools B and R, enhancing performance by ensuring faster and more consistent response times, especially when used as pilot controls where capacity is less critical. The DMDATNN228 operates without requiring a minimum hydraulic pressure, which allows for flexible installation and use in various hydraulic systems. It includes options for manual overrides with D or L controls; however, these are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve also features EPDM seals configured specifically for systems using phosphate ester fluids; caution is advised as exposure to petroleum-based fluids can damage these seals. Additionally, the wet armature design of this model means that the working fluid surrounds the armature which can be subjected to heat during prolonged coil energization\u2014this should be considered in applications involving temperature-sensitive fluids. The interchangeable coils compatible with other Sun Series 1 solenoid products offer versatility in maintenance and replacement. Furthermore, Sun Hydraulics incorporates a floating style construction in this model to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This model supports up to 12 gpm (45 L/min) capacity and has typical response times of 50 ms. Its maximum operating pressure capability stands at 5000 psi (350 bar), with maximum valve leakage noted at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Designed for both reliability and efficiency in complex hydraulic setups, the DMDATNN228 provides an effective solution for directional control challenges.

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.
