The Sun Hydraulics DMDAXBN848 (DMDAXBN848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to be highly efficient and reliable in various hydraulic applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it meets the demanding requirements of industrial hydraulic systems. The DMDAXBN848 features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi, ensuring durability and longevity under high-pressure conditions. The closed transition between Spools B and R enhances performance by providing faster and more consistent response times, particularly advantageous when used as pilot controls where capacity is not a critical factor. This model incorporates manual override options with detent mechanisms designed for temporary actuation, supporting approximately 7,000 cycles mechanically. It also uses EPDM seals specifically for compatibility with phosphate ester fluids, while exposure to petroleum-based products should be avoided to prevent seal damage. A notable design aspect of the DMDAXBN848 is its wet armature setup, where the working fluid surrounds the armature. This arrangement necessitates consideration of fluid type as certain fluids may degrade at higher temperatures induced by prolonged coil energization. Additionally, this valve model embraces Sun's floating style construction which minimizes internal parts binding\u2014a common issue resulting from excessive installation torque or variations in cavity/cartridge machining. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility in maintenance and replacement processes. This robust construction combined with precise engineering makes the DMDAXBN848 an excellent choice for enhancing hydraulic system efficiency 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.
