The Sun Hydraulics DMDAXRN223 (DMDAXRN223) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is well-suited for applications requiring reliable control of hydraulic flow. The valve features a fatigue rating of 5000 psi (350 bar), making it robust for demanding environments. The DMDAXRN223 utilizes B and R spools that are closed in the transition between two positions, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. Its direct actuation does not require minimum hydraulic pressure for operation, offering versatility across various hydraulic systems. This model includes manual override options with a detent mechanism designed for temporary actuation. The mechanical life expectancy of these manual controls is about 7,000 cycles. Additionally, the valve incorporates EPDM seals suitable for phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. A notable feature of the DMDAXRN223 is its wet armature design which allows the working fluid to surround the armature and manage heat during prolonged energization\u2014important in preventing breakdowns or varnish formation from certain hydraulic fluids like water-glycol mixtures. Furthermore, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also benefits from Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), along with a quick typical response time of 50 ms and maximum switching frequency of 15000 cycles/hr, this valve is engineered to meet rigorous industrial demands efficiently and reliably.
