The Sun Hydraulics DMDAXBN224N (DMDAXBN224N) 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 design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve's spools B and R are closed in the transition between their two positions, enhancing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The DMDAXBN224N requires no minimum hydraulic pressure to operate and incorporates an innovative wet armature design where the working fluid surrounds the armature. This design aspect is crucial as it affects heat management when the coil is energized over extended periods. The valve supports a flow capacity of 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). It also features interchangeable coils with other Sun Series 1 solenoid products, adding to its versatility. For manual operation, models equipped with D or L control offer a detent mechanism in the manual override intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. Additionally, this model utilizes EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids which could damage the seals. Overall dimensions include a solenoid tube diameter of .75 inches (19 mm) and an installation torque requirement between 30 - 35 lbf.ft (41 - 47 Nm). The valve's quick response time of typically 50 ms and switching frequency up to 15,000 cycles/hr make it an efficient choice for various hydraulic applications requiring reliable and rapid directional control.

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.
