The Sun Hydraulics DMDADPN814N (DMDADPN814N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is well-suited for applications requiring precise flow direction control with minimal hydraulic pressure to operate. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it ideal for high-pressure systems. The DMDADPN814N incorporates closed transitions between spools B and R, enhancing performance by allowing faster and more consistent response times especially in pilot control applications where capacity is less critical. This model also supports manual override through a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of the valve ensures that the working fluid surrounds the armature and mitigates potential overheating issues when the coil is energized for extended periods. However, users should be cautious with fluids like water-glycol mixtures that may degrade under sustained high temperatures. With a flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this model ensures efficient operation across various applications. The interchangeable coils of the Sun Series 1 solenoid products add to its versatility, allowing mounting in either direction on the tube. Additionally, Sun Hydraulics' floating style construction minimizes internal part binding due to installation torque or machining variations in cavity/cartridge setups.
