The Sun Hydraulics DMDADRV212N (DMDADRV212N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve is adept at handling a maximum operating pressure of 5000 psi (350 bar), making it suitable for heavy-duty operations. The valve features a unique closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times during pilot controls operations where capacity is less critical. With a flow capacity of up to 12 gpm (45 L/min), the DMDADRV212N ensures efficient fluid management in various hydraulic systems. It incorporates a wet armature design allowing the working fluid to surround the armature, which can be critical in managing the heat generated by the coil during prolonged energization. This design consideration is essential when using certain fluids like water-glycol mixtures that may degrade under high temperatures. The valve's construction benefits from Sun's floating style design which minimizes internal parts binding that could result from excessive installation torque or variances in cavity/cartridge machining. It also features interchangeable coils with other Sun Series 1 solenoid products, enhancing its adaptability and ease of maintenance. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. Additionally, the manual override feature includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Overall, the DMDADRV212N offers robust construction and versatile performance capabilities suited for demanding hydraulic applications requiring precise control and reliability.

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.
