The Sun Hydraulics DMDADNN4E12V (DMDADNN4E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered to operate effectively without minimum hydraulic pressure, enhancing its versatility in various operational settings. Featuring a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), it ensures reliability under high-pressure conditions. The DMDADNN4E12V model incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times at the expense of lower capacity\u2014ideal for pilot control applications where capacity is less critical. The manual override in models with D or L control includes a detent mechanism intended for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. Designed with EPDM seals, this cartridge is suitable for systems using phosphate ester fluids while avoiding exposure to petroleum-based fluids which could damage the seals. The wet armature design of the valve allows the working fluid to surround the armature; however, prolonged energization should be monitored as it can lead to breakdowns in certain fluid types like water-glycol mixtures. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and a floating style construction that minimizes internal parts binding due to installation variances. The valve has a maximum operating pressure of 5000 psi (350 bar), a flow capacity of 12 gpm (45 L/min), and rapid response times typically around 50 ms. With these specifications and robust construction, the Sun Hydraulics DMDADNN4E12V valve is well-suited for demanding hydraulic applications requiring precise control and durability.
