The Sun Hydraulics DMDAXAV628 (DMDAXAV628) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for various hydraulic applications. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility in a range of operational contexts. The valve features a fatigue rating for up to 5000 psi (350 bar), making it suitable for demanding environments. Key features of the DMDAXAV628 include closed transitions between Spools B and R, which prevent flow in the intermediate position, thus offering faster and more consistent response times particularly useful in pilot control applications where flow capacity is less critical. The model incorporates a wet armature design allowing the working fluid to surround the armature; however, this design consideration requires careful selection of fluid types to avoid breakdowns or varnish formation that could impair functionality over time. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and showcases quick response times typically around 50 ms. It can handle switching frequencies up to 15000 cycles per hour and accommodates manual override with minimal force requirements. Additionally, its floating style construction minimizes internal parts binding caused by installation torque or machining variations. For maintenance and compatibility with different system fluids, cartridges configured with EPDM seals are recommended specifically for use with phosphate ester fluids. The DMDAXAV628\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube assembly, adding to its flexibility in application and installation.

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.
