The Sun Hydraulics DMDAMBV212 (DMDAMBV212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic control. This direct-acting, balanced spool directional valve is particularly noted for its fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDAMBV212 operates without a minimum hydraulic pressure requirement, allowing for flexible integration into various hydraulic systems. It includes manual override options with a mechanical life expectancy of about 7,000 cycles, ideal for temporary actuation needs. Notably, the valve's cartridges that are configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, they must not be exposed to petroleum-based fluids as these can degrade the seals. This model also incorporates a wet armature design where the working fluid surrounds the armature. Such a setup requires consideration of the fluid type used since some fluids can degrade under prolonged heat exposure from an energized coil. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility in system design. Other technical specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a switching frequency up to 15,000 cycles per hour. The valve also features Sun's floating style construction which minimizes internal parts binding\u2014this is crucial in preventing operational inconsistencies due to installation torque or machining variations in cavity-cartridge systems.

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.
