The Sun Hydraulics DMDALNN212 (DMDALNN212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is particularly noted for its fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure operations. The DMDALNN212 features spools B and R which are closed in the transition between their two positions, enhancing performance limits at the cost of lower capacity. This characteristic is ideal for pilot controls where capacity is less critical but a fast and consistent response time is paramount. The valve operates without a minimum hydraulic pressure requirement and includes models with D or L control options, which offer a detent mechanism in the manual override designed for temporary actuation. With a mechanical life expectancy of approximately 7,000 cycles for the manual control assembly, the DMDALNN212 ensures durability and reliability in demanding settings. It also incorporates EPDM seals suitable for systems using phosphate ester fluids while cautioning against exposure to petroleum-based fluids which can damage these seals. This model utilizes a wet armature design allowing the working fluid to surround the armature; this can be a consideration if the coil remains energized over extended periods as some fluids may degrade under prolonged heat exposure. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The floating style construction minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve meets demanding operational criteria while maintaining minimal leakage and high switching frequency capabilities.
