The Sun Hydraulics DMDALNN948 (DMDALNN948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that offers precise control and durability in hydraulic systems. This direct-acting, balanced spool directional valve is designed with a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The DMDALNN948 features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model operates without the need for minimum hydraulic pressure, allowing for flexible implementation across various hydraulic systems. It includes options for manual override controls (D or L control) with a detent mechanism designed for temporary actuation, boasting a mechanical life expectancy of around 7,000 cycles. The valve is equipped with EPDM seals specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. The DMDALNN948 uses a wet armature design which involves the working fluid surrounding the armature. This design consideration is vital when the coil remains energized over extended periods as it can lead to breakdowns in certain fluid types like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, and its floating style construction minimizes internal parts binding due to installation variances. Key specifications include a flow capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at rated conditions of 5 in\u00b3/min at 3000 psi. The model also supports up to 15,000 switching cycles per hour. Installation requires specific torque settings and the manual override feature demands minimal force, ensuring ease of maintenance and operational reliability in demanding environments.
