The Sun Hydraulics DMDADAV224N (DMDADAV224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct acting and balanced spool directional control. This valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), making it robust for demanding applications. With closed transitions between Spools B and R, the DMDADAV224N ensures a higher performance limit, ideal for pilot controls where capacity is less critical but fast and consistent response times are necessary. The valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes manual override options with detent mechanisms designated for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The DMDADAV224N is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized over extended periods as it can influence fluid integrity due to heat exposure. For compatibility and maintenance ease, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also incorporates Sun\u2019s floating style construction which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of 12 gpm (45 L/min) and rapid typical response times of 50 ms, alongside maximum operating pressures of 5000 psi (350 bar), the DMDADAV224N is engineered to meet rigorous industrial demands while maintaining precise control and reliability in hydraulic systems operations.

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.
