The Sun Hydraulics DMDAMAV212N (DMDAMAV212N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Ideal for use in hydraulic systems requiring reliable and precise control, this valve features a fatigue rating for up to 5000 psi or 350 bar service. It is specifically designed with closed transitions between Spools B and R to enhance performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This direct-actuated valve operates without needing a minimum hydraulic pressure, which allows for flexibility in various application settings. It includes options for manual override through the D or L control models, which are equipped with a detent mechanism intended for temporary actuation. The mechanical life expectancy of these manual control assemblies is approximately 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as it could damage the seals. The valve\u2019s wet armature design means that the working fluid surrounds the armature which can be exposed to heat if the coil remains energized for extended periods. Additionally, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This versatility is enhanced by Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With its robust build and responsive design, the DMDAMAV212N is an excellent choice for dynamic hydraulic system applications requiring precise directional 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.
