The Sun Hydraulics DMDADAV212 (DMDADAV212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without the need for minimum hydraulic pressure, making it versatile across various applications. The valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, ensuring reliability and longevity even under demanding conditions. The DMDADAV212 incorporates closed transitions between Spools B and R which enhance performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The manual override options (D, L, and T controls) are equipped with a detent mechanism designed primarily for temporary actuation, supporting up to approximately 7,000 cycles. This model uses EPDM seals specifically suited for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. Another notable feature is its wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil remains energized over extended periods as some fluids may degrade at higher temperatures. The DMDADAV212 also benefits from interchangeable coils with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction which minimizes internal parts binding. This construction allows for more forgiving installation regarding torque and machining variations. With a maximum operating pressure of 5000 psi (350 bar), capacity of 12 gpm (45 L/min), and rapid typical response time of 50 ms, this valve is an excellent choice for advanced hydraulic system configurations requiring reliable directional control.

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.
