The Sun Hydraulics DMDALPN614 (DMDALPN614) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. Designed for direct-acting, balanced spool directional control, it features a robust construction that includes a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). This valve is particularly noted for its closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times especially in pilot control applications where capacity is less critical. The DMDALPN614 operates without the need for minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes options such as manual overrides with a detent mechanism designed for temporary actuation, suitable for models equipped with D or L control. The mechanical life expectancy of these manual controls is approximately 7,000 cycles. Additionally, the valve features EPDM seals configured specifically for use with phosphate ester fluids; these seals must avoid exposure to petroleum-based substances to prevent damage. Another key aspect of the DMDALPN614 is its wet armature design which allows the working fluid to surround the armature. This design consideration is crucial when the valve is used with fluids like water-glycol mixtures that may degrade at high temperatures. The valve supports interchangeable coils from other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation stresses or machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient operation under demanding conditions. It also supports a high switching frequency up to 15,000 cycles per hour, making it suitable for applications requiring frequent cycling under high pressure conditions.
