The Sun Hydraulics DMDALPV248 (DMDALPV248) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), suitable for demanding applications. Key to its design is the closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times ideal for pilot control systems where capacity is less critical. The DMDALPV248 operates without a minimum hydraulic pressure requirement, which simplifies integration into various hydraulic circuits. The manual override feature equipped with the D or L control uses a detent mechanism designed primarily for temporary actuation with an expected mechanical life of around 7,000 cycles. This model also incorporates EPDM seals specifically chosen for compatibility with phosphate ester fluids; however, these seals must avoid contact with petroleum-based fluids to prevent damage. A notable feature of the DMDALPV248 is its wet armature design, which allows the working fluid to surround the armature\u2014important when considering thermal management within the system. Coils used in this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. Additionally, this valve benefits from Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or cavity/cartridge machining variations. The DMDALPV248 supports up to 12 gpm (45 L/min) flow capacity and offers rapid response times typically around 50 ms. With its robust design and versatile features, this valve is engineered to meet stringent operational demands while ensuring reliability and durability in complex hydraulic systems.

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.
