The Sun Hydraulics DMDALNN512 (DMDALNN512) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliability and longevity under high-pressure operations. The valve offers distinct operational advantages with closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times particularly suitable for pilot control applications where capacity is less critical. The DMDALNN512 operates efficiently without requiring a minimum hydraulic pressure, making it versatile across various hydraulic systems. It includes manual override options with the D or L control, equipped with a detent mechanism designed for temporary actuation and an expected mechanical life of approximately 7,000 cycles. Additionally, the valve employs EPDM seals configured specifically for compatibility with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. A unique feature of this model is its wet armature design which immerses the armature in working fluid to manage heat from the coil\u2014important when considering fluid compatibility and operational longevity. The interchangeable coils compatible with other Sun Series 1 solenoid products add to the flexibility of use and installation ease. Furthermore, the design incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations. Technical specifications include a maximum flow capacity of 12 gpm (45 L/min), fast response times typically around 50 ms, and maximum operating pressures up to 5000 psi (350 bar). The valve also supports a high switching frequency up to 15,000 cycles/hr making it suitable for systems requiring frequent operation cycles. Designed for both efficiency and durability in demanding environments, this valve ensures optimal performance and reliability in controlling hydraulic flow directions within sophisticated 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.
