The Sun Hydraulics DMDALNN724 (DMDALNN724) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar). It is particularly noted for its closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times in applications where capacity is less critical. The DMDALNN724 requires no minimum hydraulic pressure to operate, making it versatile across various mechanical setups. It includes manual override options with a detent mechanism designed for temporary actuation, supporting around 7,000 cycles mechanically. The valve's configurations with EPDM seals are specifically intended for use with phosphate ester fluids; however, they must avoid exposure to petroleum-based fluids which can damage the seals. This model also employs a wet armature design wherein the working fluid surrounds the armature\u2014beneficial in reducing operational noise but requires consideration regarding fluid type due to potential breakdowns from prolonged heat exposure. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Additional features of the DMDALNN724 include a maximum flow capacity of 12 gpm (45 L/min), rapid typical response times of about 50 ms, and robust switching capabilities up to 15,000 cycles per hour. The manual override requires minimal force and has a short stroke distance, facilitating easy operation under varied pressure conditions. Installation considerations are simplified by Sun\u2019s floating style construction which minimizes internal part binding risks due to installation torque or machining variations in cavity/cartridge setups.

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.
