The Sun Hydraulics DMDAXAV212 (DMDAXAV212) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure required, which enhances its versatility in various hydraulic circuits. The DMDAXAV212 model incorporates closed transitions between spools B and R, optimizing performance by providing faster and more consistent response times, particularly useful in pilot control applications. It is equipped with manual override options (D, L, or T control) that have a mechanical life expectancy of approximately 7,000 cycles. These manual overrides are intended for temporary actuation. This valve model uses EPDM seals configured for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve allows the working fluid to surround the armature which helps in heat management but requires careful consideration of the fluid type used due to potential breakdowns at high temperatures. For ease of integration into existing systems, the coils of the DMDAXAV212 are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, Sun's floating style construction is employed to minimize internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This model has a flow capacity of up to 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). Its quick response time (typically 50 ms), along with a maximum switching frequency of 15,000 cycles per hour, makes it an efficient choice for systems requiring frequent directional changes under varying pressures.

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.
