The Sun Hydraulics DMDADNV4E12V (DMDADNV4E12V) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered to be fatigue rated for high-pressure applications up to 5000 psi (350 bar). It is characterized by its closed transitions between Spools B and R, enhancing performance limits while having a lower capacity, which is optimal when used as pilot controls for faster and more consistent response times. The valve operates without requiring a minimum hydraulic pressure, making it versatile in various hydraulic systems. This model incorporates several user-friendly features including interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override in the DMDADNV4E12V includes a detent mechanism intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It also utilizes EPDM seals suitable for phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. The wet armature design of this valve means that the working fluid surrounds the armature, which could lead to breakdowns in certain fluids under prolonged heat exposure from the coil. Additionally, the valve's construction minimizes internal parts binding due to its floating style construction that compensates for installation torque and machining variations. With a capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this cartridge valve ensures efficient operation across various hydraulic applications.

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.
