The Sun Hydraulics DMDAXPV914 (DMDAXPV914) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. Engineered for direct-acting operation, this balanced spool directional valve does not require a minimum hydraulic pressure to function effectively. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. The valve offers a rapid and consistent response time, especially beneficial when used as pilot controls where capacity is less critical. Its spools, B and R, remain closed during the transition between positions to enhance performance limits while reducing capacity. The manual override in models with D or L control is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This model utilizes EPDM seals ideal for systems running on phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The wet armature design of the valve ensures that the working fluid surrounds the armature which is critical if the coil remains energized over extended periods as heat buildup can degrade certain fluid types. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing mounting in either direction on the tube. Additionally, it incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of up to 12 gpm (45 L/min), and typical response times around 50 ms. The valve supports switching frequencies up to 15,000 cycles/hr and has manual override features requiring minimal force yet providing precise control through its .10 inch (2.5 mm) stroke. This compact unit weighs just .60 lb (0.30 kg), ensuring ease of installation with standard tools without excessive torque requirements.
