The Sun Hydraulics DMDADNV514 (DMDADNV514) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation with a fatigue rating for 5000 psi (350 bar) service. It features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. The DMDADNV514 operates without the need for a minimum hydraulic pressure, making it versatile in various applications. The manual override options available with this model include D or L control types, which are intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve\u2019s design incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. A notable design feature of the DMDADNV514 is its wet armature setup where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods due to heat exposure. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and can handle switching frequencies up to 15,000 cycles per hour. For installation flexibility, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, Sun Hydraulics has incorporated their floating style construction into this model to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This construction detail ensures reliable and efficient operation under varying mechanical conditions.
