The Sun Hydraulics DMDAXAV928 (DMDAXAV928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, ensuring reliable performance in various applications. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding environments. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, which facilitates quick and efficient operations. The valve's design minimizes internal parts binding through its floating style construction, which compensates for installation torque and cavity/cartridge machining variations. Additionally, the manual override mechanism in the D, L, and T control models offers temporary actuation with a mechanical life expectancy of about 7,000 cycles. The DMDAXAV928 incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This model also utilizes a wet armature design where the working fluid surrounds the armature\u2014important to consider if the coil remains energized for extended periods due to potential breakdowns in certain fluid types. Overall, this valve is ideal for applications requiring robust control with fast response times and high-pressure endurance while providing flexibility in manual and solenoid operations.

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.
