The Sun Hydraulics DMDAXPN724N (DMDAXPN724N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic applications. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for up to 5000 psi or 350 bar, ensuring reliable operation under high-pressure conditions. The valve's design includes closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDAXPN724N requires no minimum hydraulic pressure to operate, which simplifies integration into various systems. It includes options for manual override controls (D, L, T) with a mechanical life expectancy of around 7,000 cycles. Notably, models equipped with EPDM seals are specifically designed for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. This valve also features a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil can lead to higher fluid temperatures affecting fluid properties over time. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexible installation options and can be mounted in either direction on the tube. Additional specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min. It supports switching frequencies up to 15,000 cycles per hour and requires manual override force of about 5 lbs at 1000 psi. The unit's compact dimensions include a solenoid tube diameter of .75 inches and an overall weight of .60 lb, making it suitable for space-constrained installations while still maintaining robust performance and reliability across various hydraulic applications.
