The Sun Hydraulics DMDALNN224 (DMDALNN224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its robust construction includes a fatigue-rated solenoid tube assembly suitable for demanding applications. The DMDALNN224 offers quick and consistent response times due to its closed transition spools in positions B and R, which are particularly effective when used as pilot controls. This model is equipped with manual override options including the D or L control, which have a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature, aiding heat dissipation but requiring careful consideration of fluid type to avoid breakdown and varnish formation. It is compatible with EPDM seals for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids. Interchangeability with other Sun Series 1 solenoid products is facilitated by its coil design, which can be mounted in either direction on the tube. The valve also incorporates Sun's floating style construction to minimize internal binding caused by installation torque or machining variations. With its rapid response time typically around 50 ms and switching frequency up to 15,000 cycles/hr, the DMDALNN224 is an efficient solution for various hydraulic control applications requiring precise directional control and reliable operation under high-pressure conditions.

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.
