The Sun Hydraulics DNCALAN528 (DNCALAN528) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a closed transition between positions to minimize oil loss during shifting, enhancing performance in pilot control circuits. It operates efficiently with a capacity based on port 3 as the inlet and port 1 as the tank, although it allows reverse flow under certain conditions. The DNCALAN528 valve is notable for its robust solenoid tube assembly, which is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability even under high-pressure conditions. It requires no minimum hydraulic pressure for operation and includes EPDM seals suitable for systems using phosphate ester fluids. The wet armature design of the valve means that the working fluid surrounds the armature; this requires consideration of fluid type as some may degrade at higher temperatures. This model also offers flexibility with a variety of coil termination and voltage options available to suit different system requirements. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options provide environmental protection ratings up to IP69K. Additionally, the DNCALAN528 incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This feature ensures consistent performance and longevity of the valve in demanding operational environments. The valve's specifications include an operating capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 50 ms. It supports switching frequencies up to 15000 cycles per hour, making it highly effective for applications requiring frequent cycling under rigorous conditions.
