The Sun Hydraulics DMDALBV924N (DMDALBV924N) 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 unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control setups. The valve operates without requiring a minimum hydraulic pressure and incorporates an innovative wet armature design where the working fluid surrounds the armature, crucial for heat management but sensitive to long energization periods. Notably, the DMDALBV924N is fatigue rated for demanding 5000 psi (350 bar) service conditions and offers a flow capacity of up to 12 gpm (45 L/min). Its response time is typically swift at around 50 ms. For manual override operations, it includes a detent mechanism designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The manual override requires minimal force and has a short stroke length which ensures ease of use under varying pressure conditions. This model's compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate various installation requirements. The valve also benefits from Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue in environments with excessive installation torque or where cavity/cartridge machining variations occur. This design consideration significantly enhances the reliability and longevity of the valve in complex hydraulic setups.
