The Sun Hydraulics DMDALPN248 (DMDALPN248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). It features a rapid response time of typically 50 ms and allows for a switching frequency of up to 15,000 cycles per hour. The valve's manual override requires a force of 5 lbs at 1000 psi on Port 1, and it incorporates a stroke length of .10 inches (2.5 mm). This model utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The DMDALPN248 benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Its solenoid tube assembly is fatigue rated for demanding applications and the spools B and R are closed in transition, enhancing performance at the cost of reduced capacity. Designed with practicality in mind, the DMDALPN248's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual control assembly with D or L control features a detent mechanism intended for temporary actuation and has an estimated mechanical life expectancy of around 7,000 cycles. This valve\u2019s wet armature design means that the working fluid surrounds the armature, which could be a consideration if the coil remains energized over extended periods as it could lead to fluid breakdown in certain conditions. Overall, the Sun Hydraulics DMDALPN248 offers robust performance for specialized hydraulic applications requiring precise control and reliability 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.
