The Sun Hydraulics DMDALBN223 (DMDALBN223) 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 robust design with a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. Its closed transition spools (B and R) enhance performance by providing faster and more consistent response times, particularly useful in pilot control setups where capacity is less critical. The DMDALBN223 operates without requiring a minimum hydraulic pressure, ensuring reliable functionality across various conditions. It includes options such as the D or L control with a manual override detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. The valve is equipped with EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based substances to prevent damage. Notably, the valve incorporates a wet armature design where the working fluid surrounds the armature; this could lead to breakdowns in certain fluids if the coil remains energized extensively. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in mounting orientations. Additionally, its construction includes Sun's floating style which minimizes internal parts binding due to installation torque or machining variations. With specifications like a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, along with switching frequencies up to 15,000 cycles/hr, the DMDALBN223 is optimized for high-frequency operations where precision and durability are paramount. This model also features manual override capabilities and various installation-friendly attributes such as an accommodating valve hex size and specified installation torque ranges.

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.
