The Sun Hydraulics DMDAXNN848 (DMDAXNN848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a robust construction that is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve's spools B and R maintain a closed state during transitions between positions, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDAXNN848 operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic systems. It includes options such as the D or L control with a manual override mechanism designed primarily for temporary actuation, supporting up to approximately 7,000 cycles mechanically. Furthermore, this model can be equipped with EPDM seals suitable for phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids which can cause damage. In terms of design specifics, the DMDAXNN848 utilizes a wet armature setup where the working fluid surrounds the armature exposed to coil-generated heat. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade at high temperatures. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. This valve also incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDAXNN848 is an efficient solution for controlling fluid direction in hydraulic systems requiring high precision and reliability.

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.
