The Sun Hydraulics DNCADZV212N (DNCADZV212N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly reducing oil loss during shifting which is crucial in pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank return, although it supports reverse flow under specific conditions. With a robust capacity of 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar, the DNCADZV212N is built to handle demanding applications. Its solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long-term performance. The valve operates without requiring a minimum hydraulic pressure which enhances its versatility in various system configurations. This model features EPDM seals configured specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the solenoid means that the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods. Additionally, Sun Hydraulics has equipped this model with various coil termination and voltage options to suit different operational needs and environments. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate system requirements. High efficiency in the magnetic design of the solenoid ensures reliable valve shifting by generating strong actuating force per Watt expended. The DNCADZV212N also incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations, further enhancing its reliability and ease of use in complex hydraulic setups.
