The Sun Hydraulics DMDADAN228 (DMDADAN228) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate efficiently with no minimum hydraulic pressure required for activation, making it suitable for a wide range of applications. The unit features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The DMDADAN228 valve incorporates advanced design features such as closed transitions between spool positions B and R, which enhance performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The mechanical life expectancy of the manual control assembly (models with D, L, or T controls) is approximately 7,000 cycles, indicating robustness for manual override operations which are intended to be temporary. This model utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they will cause damage. Additionally, the valve's wet armature design allows the working fluid to surround the armature which could be a consideration if the coil remains energized over extended periods potentially affecting fluid integrity. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades. The construction includes Sun\u2019s floating style setup minimizing internal parts binding due to installation torque or machining variations of cavity/cartridge. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typical at 50 ms, this valve ensures efficient operation across various hydraulic functions. The compact size (.60 lb/0.30 kg) and specific installation requirements (torque between 30 - 35 lbf ft/41 - 47 Nm) make it easy to integrate into various systems without compromising performance.

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.
