The Sun Hydraulics DMDAXNV214 (DMDAXNV214) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool valve operates with no minimum hydraulic pressure requirement, enhancing its versatility in various applications. The valve features a robust design with a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly, making it suitable for demanding environments. The DMDAXNV214 is equipped with spools B and R that are closed during the transition between positions, which optimizes performance by providing faster and more consistent response times at the expense of lower capacity. This characteristic makes it ideal for use as pilot controls where capacity is less critical. Additionally, the model incorporates manual override options (D or L control) with a mechanical life expectancy of approximately 7,000 cycles, primarily intended for temporary actuation. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based fluids. The wet armature design of this valve ensures that the working fluid surrounds the armature which might be a consideration if the coil remains energized for extended periods due to potential breakdowns in certain fluids like water-glycol mixtures. Interchangeable coils from Sun Series 1 solenoid products add to the flexibility and ease of maintenance of this valve. Furthermore, its construction includes Sun's floating style which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDAXNV214 offers reliable performance in precision hydraulic control applications.
