The Sun Hydraulics DNCADXN712N (DNCADXN712N) is a high-performance, solenoid-operated directional valve designed for precision hydraulic control. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with a closed transition between positions, minimizing oil loss during shifting. This characteristic is particularly beneficial in pilot control circuits where maintaining fluid integrity is crucial. With a capacity of 8 gpm/30 L/min and an impressive maximum operating pressure of 5000 psi/350 bar, the DNCADXN712N is well-suited for demanding applications. The valve operates efficiently with no minimum hydraulic pressure required for activation, thanks to its direct-actuated design. It incorporates EPDM seals specifically for use with phosphate ester fluids, although it's important to avoid contact with petroleum-based substances to prevent seal damage. The DNCADXN712N employs a wet armature design where the working fluid surrounds the armature. This setup can influence fluid integrity if the coil remains energized for extended periods, especially in scenarios involving water-glycol mixtures which may degrade and form varnishes at high temperatures. To accommodate various operational needs and environments, Sun Hydraulics offers a range of coil termination and voltage options for this model, including designs with surge protection and up to IP69K ratings. This valve also benefits from Sun's floating style construction which reduces the risk of internal parts binding due to installation or machining discrepancies. The robust magnetic design of the solenoid ensures high efficiency and reliable spool actuating force per Watt expended, promoting consistent performance across numerous cycles (rated at 15,000 cycles/hr). With interchangeable coils compatible with other Sun Series 1 solenoid products and multiple environmental protection options available, the DNCADXN712N offers versatility alongside its powerful specifications.
