The Sun Hydraulics DMDAXNN528 (DMDAXNN528) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its reliability and versatility in various applications. Its robust construction includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability under demanding conditions. The DMDAXNN528 features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The valve's wet armature design allows the working fluid to surround the armature, which is crucial for applications where the coil may be energized for extended periods. However, users should note that certain fluids may degrade at higher temperatures caused by prolonged coil activation. This model is compatible with EPDM seals suited for systems utilizing phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. For ease of maintenance and adaptability, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include a manual override mechanism designed primarily for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The DMDAXNN528 also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This model supports up to 12 gpm (45 L/min) capacity and has a maximum operating pressure of 5000 psi (350 bar), making it a reliable choice for complex hydraulic systems requiring precise control and high-pressure tolerance.

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.
