The Sun Hydraulics DMDATPV212N (DMDATPV212N) is a solenoid-operated 3-way, 2-position cartridge valve that excels in delivering precise control and reliable operation in hydraulic systems. This direct-acting, balanced spool directional valve is designed with a fatigue rating suitable for 5000 psi (350 bar) service, making it robust for high-pressure applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. The DMDATPV212N operates without the need for minimum hydraulic pressure, ensuring effective functionality across a range of conditions. It includes options for manual override with a detent mechanism intended for temporary actuation; these models are expected to sustain mechanical life up to approximately 7,000 cycles. Special attention is needed regarding seal choices; cartridges equipped with EPDM seals are specifically designed for systems using phosphate ester fluids and should avoid contact with petroleum-based substances to prevent damage. This model also incorporates a wet armature design where the working fluid surrounds the armature, which could be a consideration if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures. The interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this component, allowing for easier maintenance and replacement processes. Further enhancing its reliability, the DMDATPV212N uses Sun's floating style construction which minimizes internal parts binding caused by installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is an efficient choice for sophisticated hydraulic systems requiring precise directional control.

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.
