The Sun Hydraulics DMDADPN223 (DMDADPN223) 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 is engineered to operate without minimum hydraulic pressure, enhancing its versatility in various operational environments. The valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Key specifications include a maximum operating capacity of 12 gpm (45 L/min) and a swift response time of approximately 50 ms, which facilitates quick and efficient system operations. The DMDADPN223 incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding, a common issue in valves due to installation torque or cavity/cartridge machining variations. The manual override feature included in this model has a mechanical life expectancy of about 7,000 cycles, with temporary actuation facilitated by the D or L control detent mechanism. The valve's wet armature design means that the working fluid surrounds the armature; this design consideration is crucial for managing the heat generated by the coil during prolonged energization. Cartridges equipped with EPDM seals are specifically intended for systems using phosphate ester fluids; however, they are susceptible to damage if exposed to petroleum-based fluids. For maintenance or customization needs, the coils of the DMDADPN223 are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This flexibility allows for easier adaptation to different system requirements or replacements.
