The Sun Hydraulics DNCALCN528 (DNCALCN528) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with closed transition. This design significantly reduces the loss of oil during shifting, which is crucial in pilot control circuits. The valve's operation does not require a minimum hydraulic pressure, making it versatile for various applications. It is designed for a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min), based on port 3 as the inlet and port 1 as the tank. This model incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to heat for extended periods. The DNCALCN528 is equipped with EPDM seals suitable for phosphate ester fluids but incompatible with petroleum-based fluids which can damage these seals. The valve's solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi (350 bar). It features an efficient magnetic design that ensures high spool actuating force per Watt expended, promoting reliable valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. For environmental protection and operational reliability in various conditions, the valve offers multiple coil termination and voltage options including models with surge protection and weatherized kits. Additionally, it incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. With rapid response times typically around 50 ms and capable of handling up to 15,000 switching cycles per hour, this model ensures robust performance in demanding applications. Its manual override features require minimal force and provide precise control over operations. This makes the DNCALCN528 an ideal choice for systems requiring reliable directional control in hydraulic circuits.
