The Sun Hydraulics DMDALRN248 (DMDALRN248) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control in hydraulic systems. It features a robust construction with a fatigue rating of 5000 psi (350 bar), suitable for demanding applications. The valve operates without the need for a minimum hydraulic pressure, enhancing its efficiency and reliability across various operational conditions. This model is equipped with interchangeable coils from the Sun Series 1 solenoid products, allowing for flexibility in maintenance and replacement. The coils can be mounted in either direction on the tube, simplifying installation processes. Additionally, the DMDALRN248 incorporates Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. The valve's manual override feature is designed with a detent mechanism intended for temporary actuation, supporting approximately 7,000 cycles of mechanical life expectancy. It also features EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. With a maximum operating pressure of 5000 psi (350 bar) and a typical response time of 50 ms, the DMDALRN248 ensures quick and effective performance in controlling fluid direction within hydraulic circuits. Its design also supports a maximum flow capacity of 12 gpm (45 L/min), making it suitable for various medium-scale hydraulic applications where precision and reliability are critical.

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.
