The Sun Hydraulics DMDATNV212 (DMDATNV212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and precise control in hydraulic systems. It features a fatigue-rated solenoid tube assembly that can handle up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve offers closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power contexts. It includes manual override options with a detent mechanism designed for temporary actuation, supporting around 7,000 cycles mechanically. The DMDATNV212 is equipped with EPDM seals appropriate for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature, which could be a consideration during extended periods of coil energization due to potential heat effects on certain fluids. Additionally, this model maintains compatibility with other Sun Series 1 solenoid products concerning interchangeable coils that can be mounted in either direction on the tube. Key specifications include a flow capacity of 12 gpm (45 L/min), quick response times typically around 50 ms, and very low leakage rates at high pressures. It also supports switching frequencies up to 15,000 cycles per hour and has manual override features that require minimal force. Constructed using Sun's floating style design minimizes internal part binding risks due to installation or machining variances. This compact and efficient valve is ideal for sophisticated hydraulic systems requiring reliable directional control and rapid switching capabilities.
