The Sun Hydraulics DMDALNN824 (DMDALNN824) is a highly efficient, solenoid-operated 3-way, 2-position cartridge valve. Designed for robust performance, it features a direct-acting, balanced spool directional control that operates seamlessly without the need for minimum hydraulic pressure. This model is particularly noted for its fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve's construction ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. Additionally, the DMDALNN824 includes manual override options with a detent mechanism designed for temporary actuation. The manual control assembly boasts a mechanical life expectancy of about 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of this model helps manage heat dissipation around the coil but requires consideration of fluid types as some may degrade under prolonged exposure to heat. Interchangeability is a key feature with this model as its coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Installation reliability is further enhanced by Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, along with a robust switching frequency up to 15,000 cycles/hr, the DMDALNN824 is designed to meet demanding operational criteria efficiently and reliably in various 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.
