The Sun Hydraulics DNCALAV4E12V (DNCALAV4E12V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The valve's operation does not require minimum hydraulic pressure, enhancing its flexibility and performance in various applications. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and capable of accommodating up to 8 gpm (30 L/min), the DNCALAV4E12V is robust and suitable for high-pressure tasks. The solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability under strenuous conditions. Additionally, the valve incorporates Sun's floating style construction which prevents internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. The DNCALAV4E12V offers multiple coil termination and voltage options, some with surge protection, providing adaptability to different electrical systems while maintaining efficiency and safety standards up to IP69K. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This versatility extends to environmental protection with options for weatherized coils and kits available. This model's innovative design includes a wet armature setup where the working fluid surrounds the armature. Although this design aids in efficient heat transfer when the coil is energized continuously, it requires careful consideration of fluid selection as some may degrade under prolonged exposure to heat. The DNCALAV4E12V also features rapid response times typical at 50 ms and supports switching frequencies up to 15000 cycles per hour. Its manual override capabilities ensure it can still operate during electrical power issues, making it an excellent choice for systems requiring reliable manual intervention capabilities.
