The Sun Hydraulics DMDAXAVHN24AB (DMDAXAVHN24AB) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. Featuring a direct-acting, balanced spool, this valve ensures reliable operation with no minimum hydraulic pressure required. It is particularly effective in applications requiring fast response times and consistent performance due to its closed transition between spool positions B and R, which prevents flow in the intermediate position. With a robust design that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, the DMDAXAVHN24AB is built to withstand demanding operational conditions. The valve's wet armature design allows the working fluid to surround the armature, aiding heat dissipation when the coil is energized for extended periods. However, care must be taken with fluid selection as some may degrade under prolonged exposure to heat. This model accommodates flow rates up to 12 gpm (45 L/min) and features quick response times typically around 50 ms. It supports switching frequencies up to 15,000 cycles per hour, making it suitable for high-cycle applications. Manual override options are available with a force requirement of approximately 5 lbs at 1000 psi for port adjustments. The valve\u2019s manual override mechanism is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. Additionally, the interchangeable coils from Sun Series 1 solenoid products add flexibility and ease of maintenance by allowing mounting in either direction on the tube. This valve also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation variances or machining inconsistencies.
