The Sun Hydraulics DMDALNN524 (DMDALNN524) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures precise control with its fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar). The B and R spools in this model are closed during the transition between two positions, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDALNN524 requires no minimum hydraulic pressure to operate, which enhances its versatility in various hydraulic systems. It features manual override options with a detent mechanism designed for temporary actuation, ensuring reliability with a mechanical life expectancy of approximately 7,000 cycles. The valve is equipped with EPDM seals specifically intended for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Further enhancing its functionality, the DMDALNN524 incorporates a wet armature design allowing the working fluid to surround the armature. This design consideration is crucial when the coil is energized for extended periods as some fluids may degrade under prolonged exposure to heat. The valve also supports interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. With a capacity of 12 gpm (45 L/min) and quick response time of approximately 50 ms, this valve stands out for its efficiency and reliability in demanding applications.

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.
