The Sun Hydraulics DMDAXBV223 (DMDAXBV223) 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 features a unique construction that includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve operates efficiently with no minimum hydraulic pressure required for activation, making it versatile across various operating environments. Equipped with closed transitions between Spools B and R, the DMDAXBV223 offers enhanced performance limits by ensuring faster and more consistent response times during operation, which is particularly beneficial in pilot control applications where capacity is less critical. The manual override feature incorporated in this model uses a detent mechanism designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. This model can be configured with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they will cause damage. The wet armature design of the valve ensures the working fluid surrounds the armature which helps in heat management but could affect fluid integrity if exposed to prolonged high temperatures. The DMDAXBV223 is compatible with other Sun Series 1 solenoid products regarding coil interchangeability and can be mounted on the tube in either direction. It also incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), quick response times typically around 50 ms, and maximum operating pressures up to 5000 psi (350 bar). The design also supports frequent switching up to 15,000 cycles per hour, making it suitable for systems requiring high cycling frequency.
