The Sun Hydraulics DMDADBN712 (DMDADBN712) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve is engineered to operate without the need for a minimum hydraulic pressure, making it exceptionally versatile for use in different system conditions. It features a robust design with a fatigue rating of 5000 psi (350 bar), suitable for demanding operational environments. The DMDADBN712 valve offers closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The model incorporates Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque variations or cavity/cartridge machining discrepancies. This construction feature enhances the reliability and longevity of the valve under varied mechanical stresses. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products, providing flexibility and ease of maintenance with the ability to mount coils in either direction on the tube. The wet armature design employed allows the working fluid to surround the armature, which is advantageous for heat dissipation but requires consideration regarding fluid selection as certain fluids may degrade at higher temperatures. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve is an efficient solution for a variety of hydraulic control tasks. The manual override feature includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles.

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.
