The Sun Hydraulics DMDALRV948 (DMDALRV948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient control in hydraulic systems. It features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve offers closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially in pilot control applications where capacity is less critical. The DMDALRV948 operates without the need for minimum hydraulic pressure, facilitating its use in a variety of system conditions. It includes manual override options with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles mechanically. This model uses EPDM seals specifically for systems utilizing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Additionally, the wet armature design of the valve allows the working fluid to surround the armature which may expose it to heat during prolonged energization\u2014this should be considered when using certain fluids like water-glycol mixtures that may degrade under high temperatures. The interchangeable coils with other Sun Series 1 solenoid products provide flexibility in maintenance and replacement procedures. The construction of the valve incorporates Sun\u2019s floating style design which minimizes internal binding due to installation variances or excessive torque. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response times of around 50 ms. The valve also supports switching frequencies up to 15,000 cycles per hour and features manual override capabilities that require minimal force. Its compact design results in a lightweight model at just 0.60 lb (0.30 kg), ensuring ease of installation with recommended torque settings between 30 \u2013 35 lbf ft (41 \u2013 47 Nm).
