The Sun Hydraulics DMDADBN4E12V (DMDADBN4E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial use. The valve operates with no minimum hydraulic pressure required, enhancing its reliability and responsiveness. Engineered for efficiency, the DMDADBN4E12V incorporates closed transitions between Spools B and R, which minimizes capacity but maximizes performance limits, particularly beneficial in pilot control setups where speed and consistency are crucial. The manual override options available with this model include D or L control, which have a mechanical life expectancy of around 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. This model also employs a wet armature design; thus, the armature is immersed in the working fluid which helps manage heat during prolonged coil energization but requires careful consideration of fluid type to avoid breakdowns that could impair operation. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexible installation options. The construction features Sun's floating style to reduce internal part binding caused by installation torque or machining variations. With a typical response time of 50 ms and a maximum operating pressure of 5000 psi (350 bar), along with other detailed specifications like a flow capacity of up to 12 gpm (45 L/min), this valve ensures robust performance in demanding 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.
