The Sun Hydraulics DMDAXNV (DMDAXNV) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve ensures precise control with its closed spool transitions between positions, optimizing performance by minimizing flow capacity only when necessary. It is particularly effective as pilot controls due to its fast and consistent response times without requiring a minimum hydraulic pressure for operation. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity up to 12 gpm (45 L/min), the DMDAXNV can handle rigorous industrial applications. The valve features interchangeable coils from Sun Series 1 solenoid products and includes manual override options with a detent mechanism designed for temporary actuation. Notably, the valve's manual override has an expected mechanical life of about 7,000 cycles. The construction incorporates Sun's floating style to prevent internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Additionally, the wet armature design surrounds the armature with working fluid which helps in heat management but requires consideration regarding fluid selection since some fluids may degrade at higher temperatures. This model uses EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For maintenance or replacements, specific seal kits are available like Viton: 990411006 for the cartridge and Viton: 990770006 for the coil. Overall, the Sun Hydraulics DMDAXNV offers robust construction and versatile application options making it suitable for various hydraulic control systems where reliability and performance are critical.

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.
