The Sun Hydraulics DNCADZN4E12V (DNCADZN4E12V) 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 features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a critical advantage in pilot control circuits. The DNCADZN4E12V is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min), making it ideal for various demanding applications. This valve is particularly noted for its robust solenoid tube assembly that is fatigue rated for high-pressure service. It operates effectively without any minimum hydraulic pressure requirement and incorporates EPDM seals configured specifically for systems using phosphate ester fluids. Users should avoid exposure to petroleum-based fluids as they can damage the seals. The wet armature design of the valve ensures that the working fluid surrounds the armature, which may need consideration if the coil remains energized over extended periods due to potential heat-related fluid degradation. Offering flexibility in system design, the DNCADZN4E12V features a variety of coil termination and voltage options, including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this model benefits from Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With its rapid response time of approximately 50 ms and capable of up to 15,000 switching cycles per hour, this valve ensures reliable performance and durability in complex hydraulic setups. The availability of additional weatherized coils and kits further enhances its suitability for environments requiring more stringent environmental protection.
