The Sun Hydraulics DMDAXAV299 (DMDAXAV299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient control in hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it meets the demands of various hydraulic applications requiring precise control. The DMDAXAV299 features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times especially in pilot control applications where flow capacity is less critical. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability under strenuous conditions. It does not require a minimum hydraulic pressure to operate, which allows for flexibility in application. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design aids in heat management around the coil but requires consideration of fluid compatibility to prevent breakdowns. This model also incorporates interchangeable coils from Sun\u2019s Series 1 solenoid products and benefits from Sun's floating style construction which minimizes internal parts binding. This feature is crucial for maintaining consistent performance despite potential installation torque variations or cavity/cartridge machining discrepancies. With additional features like a manual override option requiring minimal force and a mechanical life expectancy of approximately 7,000 cycles for the manual control assembly, the DMDAXAV299 stands out as a reliable choice for advanced hydraulic systems needing precise directional control with robust build quality.

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.
