The Sun Hydraulics DMDAXNV848 (DMDAXNV848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that efficiently directs hydraulic flow within a system. This direct-acting, balanced spool directional valve is designed to be fatigue rated at 5000 psi (350 bar), making it suitable for rigorous applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly in pilot control applications where capacity is less critical. The DMDAXNV848 requires no minimum hydraulic pressure for operation due to its direct actuation design. It includes options for manual override controls (D, L, and T), with a mechanical life expectancy of around 7,000 cycles for the manual control assembly. This model uses EPDM seals specifically configured for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. A notable feature of the DMDAXNV848 is its wet armature design which involves the working fluid surrounding the armature, potentially affecting fluid integrity under prolonged energization. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexible installation options and are designed to minimize internal part binding through Sun's floating style construction. This valve supports a flow capacity up to 12 gpm (45 L/min) and incorporates a fast response time typically around 50 ms. It has been engineered to ensure maximum operating pressures up to 5000 psi (350 bar) with minimal leakage. The compact and robust design of the DMDAXNV848 weighs approximately 0.60 lb (0.30 kg), making it an efficient choice for various hydraulic systems requiring reliable directional control and swift actuation.
