The Sun Hydraulics DMDATRN211 (DMDATRN211) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve's spools B and R remain closed during the transition between their two positions, which enhances performance but reduces capacity. This characteristic makes it particularly suitable for pilot control applications where quick and consistent response times are critical, and capacity is less of a concern. The DMDATRN211 operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic systems. It incorporates manual override options with the D or L control, designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve is compatible with EPDM seals when used in systems containing phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids to avoid damage. Additionally, this model utilizes a wet armature design where the working fluid surrounds the armature. This setup needs consideration if the coil remains energized for extended periods as heat can cause certain fluids to degrade. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum operating pressures up to 5000 psi (350 bar). It also features Sun's floating style construction that minimizes internal part binding due to installation torque or machining variations in cavity/cartridge setups. With its compact size and efficient design, the Sun Hydraulics DMDATRN211 is engineered for precise control in advanced hydraulic systems.
