The Sun Hydraulics DMDALPN624N (DMDALPN624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically crafted to handle a maximum operating pressure of 5000 psi (350 bar) and is rated for fatigue at the same pressure level, ensuring robust performance in demanding environments. The DMDALPN624N offers a flow capacity of 12 gpm (45 L/min) and showcases quick response times, typically around 50 ms. A key aspect of this model is its closed transition between Spools B and R, which enhances performance by ensuring faster and more consistent response times during operation phases. This makes the DMDALPN624N particularly suitable for applications as pilot controls where high capacity isn't crucial but speed and reliability are. Additionally, it does not require minimum hydraulic pressure to function due to its direct actuation feature. The valve includes options for manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy up to approximately 7,000 cycles. It also incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Further enhancing its versatility, the DMDALPN624N's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction employs Sun's floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This model's thoughtful design elements ensure it meets the rigorous demands of various hydraulic applications while maintaining high durability and operational efficiency.

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.
