The Sun Hydraulics DMDAXRN624N (DMDAXRN624N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic fluid control. This direct-acting, balanced spool directional valve is specifically engineered to handle up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times during operation. Notably, the DMDAXRN624N requires no minimum hydraulic pressure to function and incorporates a wet armature design. This design allows the working fluid to surround the armature, which is essential in applications where the coil may be energized for extended periods. However, users should consider the type of fluid used as some fluids may degrade at higher temperatures caused by prolonged coil energization. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. Additionally, the manual override feature of this model has a mechanical life expectancy of approximately 7,000 cycles and is intended for temporary actuation only. The interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easy maintenance and replacement. The valve also benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Overall capacity for this model stands at 12 gpm (45 L/min) with a typical response time of 50 ms and maximum switching frequency reaching up to 15,000 cycles/hr. This makes the DMDAXRN624N an ideal choice for dynamic systems requiring precise control and rapid switching capabilities.
