The Sun Hydraulics DMDADNN211 (DMDADNN211) 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 features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The valve operates effectively without requiring a minimum hydraulic pressure, which enhances its versatility in various hydraulic circuits. With spools B and R closed during the transition between positions, the DMDADNN211 offers higher performance limits at the cost of lower capacity. This characteristic makes it particularly suitable for use as pilot controls where capacity is less critical but fast and consistent response times are necessary. The manual override feature in models with D or L control includes a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles of mechanical life. The DMDADNN211 is equipped with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, its wet armature design allows the working fluid to surround the armature which may be susceptible to heat during prolonged coil energization\u2014this should be considered when using certain fluid types like water-glycol mixtures. This valve also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding caused by excessive installation torque or machining variations of cavity/cartridge. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve meets rigorous industrial requirements while maintaining precise control and operational efficiency.
