The Sun Hydraulics DMDADPN72499 (DMDADPN72499) 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 ensures reliable control with its fatigue-rated solenoid tube assembly for pressures up to 5000 psi (350 bar). It features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes manual override options with detent mechanisms designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The DMDADPN72499 is compatible with EPDM seals specifically for use in 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 can be a consideration if the coil remains energized extensively as it may affect fluid integrity over prolonged periods. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and setup. This model also incorporates Sun\u2019s floating style construction to minimize internal parts binding due to installation variances or machining discrepancies. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). Its compact design weighs only 0.60 lb (0.30 kg) and requires manual override force of about 5 lbs at 1000 psi for port adjustments. With these features and capabilities, the Sun Hydraulics DMDADPN72499 valve offers a reliable solution for controlling flow in high-pressure hydraulic systems efficiently and effectively.
