The Sun Hydraulics DMDAMBN248 (DMDAMBN248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is built to handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 50 ms. It is particularly noted for its closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times during the shift from one position to another. The DMDAMBN248 features a wet armature design in which the working fluid surrounds the armature. This setup helps in heat management but requires careful consideration of fluid characteristics as prolonged exposure to high temperatures may lead to breakdowns or formation of varnishes. The valve's construction incorporates Sun's floating style which minimizes internal part binding due to installation torque or variations in cavity/cartridge machining. This model supports a flow capacity up to 12 gpm (45 L/min) and can be used with EPDM seals specifically designed for phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and replacement processes. The manual override feature included in models with D or L control is intended for temporary actuation, and the mechanical life expectancy for these controls is about 7,000 cycles. In summary, the Sun Hydraulics DMDAMBN248 valve is engineered for precision and durability in hydraulic systems requiring reliable directional control and rapid response times under high-pressure conditions.

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.
