The Sun Hydraulics DMDATAN612 (DMDATAN612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for versatile application in hydraulic systems. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features a unique design where spools B and R are closed during the transition between two positions, enhancing performance at the cost of lower capacity. This characteristic is particularly beneficial in pilot control applications where speed and consistency in response times are critical. The DMDATAN612 operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power contexts. It incorporates a wet armature design, where the working fluid surrounds the armature, which is crucial when considering the thermal management within the system. The valve's manual override options (D, L, and T controls) are designed with a mechanical life expectancy of about 7,000 cycles, indicating durability and reliability for temporary actuation tasks. For compatibility with different system fluids, cartridges configured with EPDM seals are recommended for use with phosphate ester fluids; however, these seals must be shielded from exposure to petroleum-based fluids to prevent damage. Additionally, this model supports interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube to accommodate varying installation needs. The construction of the DMDATAN612 utilizes Sun\u2019s floating style design which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With specifications like a flow capacity of 12 gpm (45 L/min) and typical response times of 50 ms along with switching frequencies up to 15,000 cycles/hr., this valve is optimized for robust performance and operational efficiency in demanding hydraulic settings.
