The Sun Hydraulics DNCALBN4E24V (DNCALBN4E24V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, which is crucial for minimizing oil loss during shifts\u2014a feature particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though it does allow reverse flow under specific conditions. Rated for fatigue at 5000 psi (350 bar), the DNCALBN4E24V operates without requiring a minimum hydraulic pressure, making it versatile and efficient in various setups. It features EPDM seals configured for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids to avoid damage. The wet armature design of the valve means the armature is surrounded by working fluid which can heat up during prolonged coil energization\u2014this needs consideration regarding fluid selection to prevent breakdown and varnish formation. The solenoid of this model boasts a unique magnetic design that enhances efficiency by delivering high spool actuating force per watt expended, ensuring reliable valve shifting. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and offer flexibility in mounting orientation. Various coil termination options are available to suit different environmental requirements with protection ratings up to IP69K. Sun Hydraulics has incorporated its floating style construction into the DNCALBN4E24V to reduce risks associated with internal parts binding due to installation torque or machining variations of cavity/cartridge. This model uses T31A cavity and belongs to Series 1, supporting an operational capacity of up to 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), making it suitable for robust applications requiring precise hydraulic management.
