The Sun Hydraulics DMDAMNN612N (DMDAMNN612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for various demanding hydraulic applications. The valve features a fatigue-rated solenoid tube assembly and offers a flow capacity of up to 12 gpm (45 L/min). Notably, the DMDAMNN612N incorporates closed transitions between spool positions B and R, enhancing its performance by providing faster and more consistent response times during pilot control operations, where capacity is less critical. This model is directly actuated and operates without requiring a minimum hydraulic pressure, ensuring reliable functionality across a range of conditions. For manual override options, the valve includes a detent mechanism designed for temporary actuation with an estimated mechanical life expectancy of around 7,000 cycles. It also uses EPDM seals configured for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances to avoid damage. The valve's design includes a wet armature setup where the working fluid surrounds the armature. This arrangement needs careful consideration as prolonged coil energization can lead to fluid degradation at high temperatures. Additionally, the DMDAMNN612N features interchangeable coils compatible with other Sun Series 1 solenoid products and employs Sun's floating style construction to minimize internal parts binding due to installation variances. This versatile valve is ideal for applications requiring precise control and robust performance in hydraulic systems. Its configuration and built-in features support efficient operation and maintenance ease, making it a valuable component in industrial 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.
