The Sun Hydraulics DMDATNV223 (DMDATNV223) 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 effectively without minimum hydraulic pressure, enhancing its versatility across various operational scenarios. The DMDATNV223 features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve's spools B and R are closed during the transition between positions, which although limits flow capacity, significantly enhances performance by providing faster and more consistent response times. This characteristic is particularly beneficial when the valve is used as a pilot control where flow capacity is less critical. Additionally, the manual override feature equipped with the D or L control is designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design allows for continuous exposure of the working fluid to the heat generated by the coil, which could affect fluid integrity over prolonged periods. Furthermore, this model supports interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal parts binding due to installation variances. With a maximum operating pressure of 5000 psi and a capacity of 12 gpm (45 L/min), alongside rapid response times typically around 50 ms and minimal leakage at high pressures, the DMDATNV223 stands out as an efficient solution in demanding hydraulic environments. Its robust design includes features like switch frequency up to 15,000 cycles/hr and manual override capabilities that require minimal force, ensuring reliable operation and ease of maintenance in industrial applications.
