The Sun Hydraulics DMDADNN948 (DMDADNN948) 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 fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly, ensuring durability under demanding conditions. It is characterized by closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. This model operates without the need for minimum hydraulic pressure, facilitating reliable performance across a range of conditions. The manual override options available with this valve include D or L control types, each designed with a detent mechanism suitable for temporary actuation and offering a mechanical life expectancy of approximately 7,000 cycles. The DMDADNN948 also utilizes EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based fluids which can damage these seals. A notable feature of this valve is its wet armature design which allows the working fluid to surround the armature. This design consideration is crucial when the coil is energized for extended periods as it can lead to breakdowns in certain fluid types such as water-glycol mixtures at elevated temperatures. For flexibility in system design, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this valve incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and typical response time of 50 ms, it offers efficient control for various hydraulic applications while maintaining minimal leakage and high switching frequency capabilities.
