The Sun Hydraulics DMDADAV4E12V (DMDADAV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is ideal for applications requiring reliable switching and control of hydraulic fluids. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it meets the demands of various high-pressure systems. The valve features a robust design with interchangeable coils from the Sun Series 1 solenoid products, which can be mounted in either direction on the tube. Its solenoid tube assembly is fatigue rated for demanding applications, ensuring longevity and consistent performance under high-pressure conditions. The DMDADAV4E12V incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Designed with a wet armature setup, the working fluid surrounds the armature which helps in heat management but requires careful selection of fluid types to avoid breakdowns or varnish formation that could impair functionality. It supports manual override with a detent mechanism intended for temporary actuation, and the manual control assembly has a mechanical life expectancy of about 7,000 cycles. This valve is particularly suited for use as pilot controls where quick and consistent response times are critical, despite its lower capacity due to closed transitions between spool positions B and R. Additionally, it requires no minimum hydraulic pressure for operation, making it versatile for various low-pressure scenarios as well. The DMDADAV4E12V is equipped with EPDM seals ideal for phosphate ester fluids but should avoid exposure to petroleum-based fluids which can damage the seals.

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.
