The Sun Hydraulics DMDAMAN912N (DMDAMAN912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic system applications. This direct-acting, balanced spool directional valve is characterized by its robust construction and efficient operation. The valve operates with a maximum capacity of 12 gpm/45 L/min and can withstand a maximum operating pressure of 5000 psi/350 bar, making it suitable for high-pressure environments. The DMDAMAN912N features a closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. Its solenoid tube assembly is fatigue rated for demanding conditions, ensuring long-term reliability even under continuous use. This model incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to installation torque or variations in cavity/cartridge machining. Additionally, the wet armature design means the working fluid surrounds the armature; this design consideration is crucial when dealing with prolonged coil energization as it affects fluid integrity over time. Moreover, the manual override feature in models equipped with D or L control uses a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. For compatibility with various systems, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, they should not be exposed to petroleum-based fluids as these could damage the seals. Interchangeability of coils with other Sun Series 1 solenoid products offers additional flexibility in maintenance and replacement procedures. With its comprehensive capabilities and robust design, the Sun Hydraulics DMDAMAN912N valve is an optimal choice for specialized hydraulic applications requiring precise control and reliability.

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.
