The Sun Hydraulics DMDATAN (DMDATAN) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies advanced hydraulic control in a compact design. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its responsiveness and reliability under a broad spectrum of operating conditions. With its fatigue rating for 5000 psi (350 bar) service, the DMDATAN is built for durability and high-performance applications. The valve features a solenoid tube assembly designed for both high-pressure endurance and optimal performance. The spools B and R maintain closure during the transition between positions, which although reduces flow capacity, significantly boosts performance by ensuring faster and more consistent response times\u2014ideal for pilot control applications where flow capacity is less critical. This model incorporates manual overrides with detent mechanisms designed primarily for temporary actuation; these are expected to last approximately 7,000 cycles. The DMDATAN uses EPDM seals suitable for systems with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the valve's wet armature design allows the working fluid to surround the armature which helps in heat management but requires consideration of fluid characteristics as prolonged exposure to heat can degrade certain types of fluids. The interchangeable coils with other Sun Series 1 solenoid products add versatility in maintenance and replacement processes. Sun Hydraulics has also integrated their floating style construction into this model to minimize internal part binding caused by installation torque or cavity/cartridge machining variations. This feature ensures consistent operation and longevity of the valve even under variable installation conditions. With specifications like a maximum operating pressure of 5000 psi, a flow capacity of up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDATAN is an exemplary choice for efficient directional control in hydraulic systems.
