The Sun Hydraulics DMDALNV714 (DMDALNV714) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, ensuring durability and reliability in demanding applications. The valve features closed transitions between its two positions (Spools B and R), which enhances performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The DMDALNV714 operates without requiring a minimum hydraulic pressure, which allows for flexibility in various hydraulic systems. It includes an optional manual override with a detent mechanism designed for temporary actuation; this feature has a mechanical life expectancy of about 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended to avoid damage from petroleum-based fluids. This model also benefits from a wet armature design where the working fluid surrounds the armature. Such design considerations are crucial when the coil remains energized for extended periods as they prevent breakdowns from heat exposure. Additionally, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has incorporated their floating style construction into this model to minimize internal parts binding that could occur due to excessive installation torque or cavity/cartridge machining variations. With a flow capacity of up to 12 gpm (45 L/min), and typical response times around 50 ms, this valve is an efficient choice for various hydraulic applications requiring robust control and fast actuation.
