The Sun Hydraulics DMDALAV914N (DMDALAV914N) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is characterized by its robust construction, with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. It incorporates a unique feature where spools B and R are closed during the transition between positions, enhancing performance at the cost of lower capacity. This attribute makes it particularly effective when used as pilot controls, delivering faster and more consistent response times due to the closed transition. The DMDALAV914N requires no minimum hydraulic pressure for operation and includes manual override options with a detent mechanism for temporary actuation. The manual control assembly boasts a mechanical life expectancy of around 7,000 cycles. The valve is equipped with EPDM seals suitable for phosphate ester fluids; however, these seals are sensitive to exposure to petroleum-based fluids which can cause damage. Featuring a wet armature design, this model allows the working fluid to surround the armature, thus being exposed to heat generated by the coil\u2014something to consider if the coil remains energized over extended periods. The interchangeable coils with other Sun Series 1 solenoid products offer versatile mounting options and minimize internal parts binding through Sun's floating style construction. This model fits into T11A cavities and operates efficiently up to a maximum pressure of 5000 psi (350 bar), handling fluid capacities up to 12 gpm (45 L/min). With rapid response times typically around 50 ms and maximum switching frequencies reaching up to 15,000 cycles per hour, this valve ensures reliable performance in demanding applications.
