The Sun Hydraulics DMDALPN548 (DMDALPN548) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust and efficient control in hydraulic systems. The valve operates with a maximum capacity of 12 gpm/45 L/min and can handle pressures up to 5000 psi/350 bar. Its rapid response time of approximately 50 ms ensures quick and precise operation. This model features a wet armature design, meaning the working fluid surrounds the armature which is beneficial for heat dissipation but requires careful selection of fluid to avoid degradation at high temperatures. It is compatible with EPDM seals suited for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The DMDALPN548 incorporates interchangeable coils that are compatible with other Sun Series 1 solenoid products, offering flexibility in system design and maintenance. The manual override feature included in this model requires a force of about 5 lbs at 1000 psi for actuation and has a stroke measurement of .10 inches. Additionally, the valve utilizes Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. This model's robust construction includes features like a maximum switching frequency of 15,000 cycles per hour and a mechanical life expectancy for the manual control assembly around 7,000 cycles, making it suitable for high-duty applications. Each unit weighs approximately .60 lb/0.30 kg and requires an installation torque between 30 - 35 lbf ft/41 - 47 Nm. The compact dimensions include a solenoid tube diameter of .75 inches and hex size of .78 inches, ensuring it fits seamlessly into various machine designs without requiring extensive space.

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.
