The Sun Hydraulics DMDAXNV612N (DMDAXNV612N) 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 capacity of 12 gpm (45 L/min), the valve is well-suited for demanding applications requiring precise fluid control. The DMDAXNV612N features a fatigue-rated solenoid tube assembly and closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times without sacrificing capacity when used as pilot controls. This model is directly actuated and operates independently of hydraulic pressure levels, making it versatile for various installation scenarios. It includes manual override options with a detent mechanism designed for temporary actuation, supporting roughly 7,000 cycles mechanically. The valve is equipped with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. Additionally, the DMDAXNV612N incorporates a wet armature design where the working fluid surrounds the armature which might be susceptible to heat during prolonged energization\u2014important to consider in systems using sensitive fluids. The coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in cavity-cartridge 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.
