The Sun Hydraulics DMDAXAV712N (DMDAXAV712N) 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 ensures reliable operation with no minimum hydraulic pressure required for functionality. It features a robust design with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. The valve operates with a switching frequency of up to 15,000 cycles per hour and has a typical response time of 50 ms. It supports a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures of 5000 psi (350 bar). The manual override feature includes a detent mechanism designed for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. Equipped with EPDM seals, the DMDAXAV712N is compatible with systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The design incorporates interchangeable coils from Sun Series 1 solenoid products and features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This valve's wet armature design allows the working fluid to surround the armature, which helps in heat management but requires consideration regarding the type of fluid used due to potential breakdowns at high temperatures. Overall, the DMDAXAV712N offers a combination of durability, reliability, and performance suited for various hydraulic applications where precision and control are necessary.

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.
