The Sun Hydraulics DMDAXAV72499 (DMDAXAV72499) 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 operates without the need for minimum hydraulic pressure, enhancing its responsiveness and reliability across various applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it is well-suited for demanding environments. The valve features closed transitions between positions B and R, which minimizes spool movement and increases performance limits while sacrificing some capacity. This characteristic makes it ideal for pilot control applications where rapid and consistent response times are critical. The DMDAXAV72499 incorporates a wet armature design, allowing the working fluid to surround the armature, which can be beneficial or detrimental depending on the duration the coil is energized and the type of fluid used. For enhanced durability and ease of maintenance, the valve's solenoid tube assembly is fatigue rated for high-pressure service. It also offers interchangeable coils with other Sun Series 1 solenoid products, providing flexibility in system design and upgrades. Furthermore, this model employs Sun\u2019s floating style construction to prevent internal parts binding caused by excessive installation torque or machining variations in cavity/cartridge. Equipped with EPDM seals specifically for use with phosphate ester fluids, this valve ensures compatibility and longevity within chemically aggressive environments. However, exposure to petroleum-based fluids should be avoided as it can damage the seals. Overall, the Sun Hydraulics DMDAXAV72499 delivers robust performance and reliable operation for specialized hydraulic applications requiring meticulous 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.
