The Sun Hydraulics DMDALAN248 (DMDALAN248) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate efficiently without requiring a minimum hydraulic pressure. The valve's solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. Featuring closed transitions between its two positions (Spools B and R), the DMDALAN248 offers enhanced performance by delivering faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The manual override included in models with D or L control utilizes a detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Additionally, the wet armature design of the valve means that the working fluid surrounds the armature which could be susceptible to heat during prolonged energization\u2014this may affect performance if using certain fluids like water-glycol mixtures. The DMDALAN248 can handle a flow capacity of up to 12 gpm (45 L/min) and features interchangeable coils that are compatible with other Sun Series 1 solenoid products. These coils can be mounted on either direction on the tube. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to installation variances or excessive torque. This model ensures robust performance with typical response times around 50 ms and supports switching frequencies up to 15,000 cycles per hour.
