The Sun Hydraulics DMDAMAV2E12V (DMDAMAV2E12V) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design for efficient directional control in hydraulic systems. This model is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It boasts rapid response times with typical switch times around 50 ms, making it suitable for applications requiring quick actuation. The valve's construction includes a wet armature design, where the working fluid surrounds the armature. While this design helps in heat dissipation during operation, it also means that the fluid's properties are crucial, especially since some fluids may degrade under prolonged exposure to heat. The DMDAMAV2E12V can accommodate various fluids but is particularly configured with EPDM seals for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based products. A notable feature of this model is its compatibility with other Sun Series 1 solenoid products concerning coil interchangeability and mounting flexibility. Additionally, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue due to installation torque or cavity/cartridge machining variations. This valve also offers manual override options with detent mechanisms designed for temporary actuation. The manual control assembly has a mechanical life expectancy of about 7,000 cycles. The overall robust construction and thoughtful engineering make the DMDAMAV2E12V an effective solution for varied hydraulic system applications requiring reliable directional control and fast response times.

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.
