The Sun Hydraulics DMDAXRN628 (DMDAXRN628) is a solenoid-operated 3-way, 2-position cartridge valve, designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is suitable for use in applications requiring precise control over fluid direction and flow. The valve features a fatigue rating of 5000 psi (350 bar), making it robust enough for demanding applications. Its design includes closed transitions between spool positions B and R to enhance performance by providing faster and more consistent response times, especially useful in pilot control setups where capacity isn't a critical factor. The DMDAXRN628 operates without the need for minimum hydraulic pressure, adding to its versatility across various hydraulic systems. It incorporates a wet armature design where the working fluid surrounds the armature, which can be crucial when the coil is energized over extended periods. This model also supports interchangeable coils with other Sun Series 1 solenoid products and offers flexible mounting options. For durability in different environments, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The manual override feature includes a detent mechanism meant for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The valve's construction benefits from Sun's floating style which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations, ensuring reliable operation and longevity. This makes the DMDAXRN628 an ideal choice for advanced hydraulic system applications requiring high reliability and precision 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.
