The Sun Hydraulics DMDALNV297 (DMDALNV297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The DMDALNV297 operates without requiring a minimum hydraulic pressure, making it versatile for different hydraulic systems. It incorporates manual override options with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The valve is equipped with EPDM seals specifically for use with phosphate ester fluids; however, they are susceptible to damage when exposed to petroleum-based fluids. Featuring a wet armature design, the DMDALNV297's working fluid surrounds the armature which can be significant when the coil is energized for extended periods as heat generated may degrade certain fluid types. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Additionally, the construction utilizes Sun's floating style to minimize internal parts binding due to installation variances or machining errors. This model has a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). With a typical response time of 50 ms and capable of handling switching frequencies up to 15000 cycles/hr, the DMDALNV297 ensures efficient and reliable operation across various high-demand applications.
