The Sun Hydraulics DMDAXNV512 (DMDAXNV512) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve ensures closed transitions between its two positions (Spools B and R), enhancing performance by providing faster and more consistent response times, especially when used as pilot controls. The DMDAXNV512 requires no minimum hydraulic pressure for operation and is equipped with a manual override that has a mechanical life expectancy of approximately 7,000 cycles. This model is particularly suited for systems using phosphate ester fluids, as it includes EPDM seals that are resistant to these types of fluids but should not be exposed to petroleum-based substances. Additionally, the wet armature design of this valve means that the working fluid surrounds the armature; this can be an essential consideration if the coil remains energized over extended periods. Furthermore, the DMDAXNV512's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This flexibility is complemented by Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), along with quick response times typical at around 50 ms, this valve is engineered for efficiency and reliability in various hydraulic setups.

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.
