The Sun Hydraulics DMDALRN224N (DMDALRN224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional design that is particularly suitable for applications requiring reliable and precise control. The valve operates with no minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It boasts a robust construction with a fatigue rating of 5000 psi (350 bar), ensuring durability under demanding conditions. This model incorporates a wet armature design where the working fluid surrounds the armature, which is crucial for applications where the valve may be energized for extended periods. However, this design necessitates careful selection of fluids to avoid breakdowns that could impair valve functionality. The DMDALRN224N is equipped with EPDM seals designed specifically for use with phosphate ester fluids; these seals are susceptible to damage when exposed to petroleum-based products. The valve offers rapid and consistent response times, credited to its closed transition spools B and R during position changes, which are essential when used as pilot controls. Additionally, it supports interchangeable coils with other Sun Series 1 solenoid products and can be installed in either direction on the tube. This model also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum switching frequency of 15000 cycles/hr. The manual override mechanism requires minimal force and provides temporary actuation capabilities, making it user-friendly in manual operations scenarios. These characteristics make the DMDALRN224N an ideal choice for sophisticated hydraulic systems requiring high performance and reliability.

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.
