The Sun Hydraulics DMDATAV812N (DMDATAV812N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic systems. This direct-acting, balanced spool directional valve is constructed to handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 50 ms, making it highly responsive for various applications. The valve features closed transitions between spools B and R, enhancing its performance by providing faster and more consistent response times especially suitable for pilot control applications where capacity isn't a critical factor. This model is equipped with interchangeable coils that are compatible with other Sun Series 1 solenoid products, allowing for flexible use and easy maintenance. The wet armature design helps in cooling but requires consideration regarding the type of fluid used, as some may degrade under prolonged exposure to heat. Specifically configured cartridges with EPDM seals are intended for systems using phosphate ester fluids, avoiding any contact with petroleum-based substances that could damage the seals. Additionally, the DMDATAV812N incorporates Sun's floating style construction which minimizes internal binding caused by installation torque or cavity/cartridge machining variations. It supports a flow capacity of up to 12 gpm (45 L/min) and can handle switching frequencies up to 15,000 cycles per hour. Manual override features require minimal force and provide temporary actuation options, enhancing operational flexibility. This model also features a manual override stroke of .10 in (2.5 mm) and can be installed using a torque range from 30-35 lbf ft (41-47 Nm), ensuring secure and reliable setup in demanding environments.

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.
