The Sun Hydraulics DMDALRN223 (DMDALRN223) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust construction that includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar). The valve ensures closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is not the primary concern. The DMDALRN223 operates without any minimum hydraulic pressure requirement and incorporates a wet armature design, which involves the working fluid surrounding the armature that could be subjected to heat during prolonged energization. This model supports a flow capacity up to 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Notably, the valve's quick response time is typically around 50 ms. Equipped with EPDM seals, this cartridge is specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids will damage these seals. For manual override operations, it includes a detent mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of the DMDALRN223 utilizes Sun\u2019s floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This design feature helps maintain reliability and extends the operational life of the component in demanding industrial settings.

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.
