The Sun Hydraulics DMDAMBN712 (DMDAMBN712) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. With its direct-acting, balanced spool directional capabilities, this model is engineered to operate efficiently with no minimum hydraulic pressure requirement. The DMDAMBN712 features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring reliable performance under demanding conditions. This valve's spools B and R maintain closure during the transition between the two positions, enhancing performance by ensuring faster and more consistent response times especially in pilot control applications where capacity is less critical. It incorporates a wet armature design where the working fluid surrounds the armature, which is crucial for applications where the coil may be energized for extended periods. Users should note that this design choice means that heat generated by the coil could affect fluid integrity over time. The DMDAMBN712 is compatible with EPDM seals specifically suited for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. The manual override feature included in models with D or L control is designed for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. For ease of integration and maintenance, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, Sun's floating style construction minimizes internal parts binding which could occur due to excessive installation torque or machining variations of cavity/cartridge. With a maximum operating pressure of 5000 psi and flow capacity of 12 gpm (45 L/min), alongside a fast typical response time of 50 ms and maximum leakage at 5 in\u00b3/min at 3000 psi, this valve stands out as an optimal solution for robust and precise hydraulic system control.
