The Sun Hydraulics DMDATNV71219 (DMDATNV71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that excels in various hydraulic applications. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and a capacity of up to 12 gpm (45 L/min), making it suitable for rigorous industrial use. The valve features unique closed transitions between Spools 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 incorporates a wet armature design allowing the working fluid to surround the armature, which is beneficial in reducing operational temperatures but requires consideration of fluid characteristics as some may degrade under prolonged exposure to heat. The DMDATNV71219 is engineered with interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction for flexible installation options. Additionally, it includes a manual override feature with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The construction utilizes Sun's floating style to minimize internal part binding due to installation variances or cavity/cartridge machining discrepancies. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids which can damage the seals. The robust design parameters of the DMDATNV71219 make it an ideal choice for applications requiring reliable directional control and rapid switching capabilities (up to 15,000 cycles per hour), all within a compact form factor that maintains minimal leakage and optimal flow characteristics under demanding conditions.
