The Sun Hydraulics DMDAXBN628 (DMDAXBN628) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. Ideal for use in applications requiring precise control and reliable operation under high-pressure conditions up to 5000 psi (350 bar), this valve is designed to perform efficiently with a maximum flow capacity of 12 gpm (45 L/min). The DMDAXBN628 utilizes a wet armature design which allows the working fluid to surround the armature, helping manage the heat generated by the coil. This design consideration is crucial when the valve operates continuously or under high temperature, as it prevents breakdown and varnishing of certain fluids. This model incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing its operational reliability and lifespan. Notably, the model is equipped with EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. The valve offers rapid response times with typical values around 50 ms and supports switching frequencies up to 15,000 cycles per hour. Additionally, it features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube for flexible installation options. The manual override option provided has a mechanical life expectancy of about 7,000 cycles and requires minimal force for operation. This makes the DMDAXBN628 versatile for various hydraulic systems where temporary manual actuation is necessary without compromising performance stability or durability.

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.
