The Sun Hydraulics DMDADNN712 (DMDADNN712) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. This valve is designed to operate without requiring a minimum hydraulic pressure, making it highly effective for various applications. The model includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. A notable feature of the DMDADNN712 is its closed transition between spools B and R, which enhances performance by providing faster and more consistent response times, ideal for pilot control applications where capacity is less critical. Additionally, the valve incorporates a manual override with a detent mechanism designed for temporary actuation, supporting an estimated mechanical life of approximately 7,000 cycles. The valve uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Its wet armature design allows the working fluid to surround the armature which could be a consideration if the coil remains energized for extended periods due to potential breakdowns in certain fluid types. Furthermore, this model's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also features Sun\u2019s floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, along with switching frequencies up to 15,000 cycles/hr, the DMDADNN712 is an adaptable solution suited for high-performance hydraulic systems requiring precise control and robust operation.
