The Sun Hydraulics DMDADNN912N (DMDADNN912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation in various hydraulic systems. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve is notable for its closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, especially in pilot control applications where capacity is less critical. This model operates without the need for minimum hydraulic pressure, adding to its versatility across different hydraulic setups. The manual override feature incorporated in the D or L control models has a mechanical life expectancy of around 7,000 cycles and is intended primarily for temporary actuation. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as it could damage the seals. The DMDADNN912N also utilizes a wet armature design which involves the working fluid surrounding the armature that could be subject to heat during prolonged coil energization. This design consideration is crucial as certain fluids might degrade under sustained heat exposure. The valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. Additionally, this model incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, the Sun Hydraulics DMDADNN912N valve ensures reliable performance and operational efficiency in demanding hydraulic applications.

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.
