The Sun Hydraulics DNCALCN4E12V (DNCALCN4E12V) 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, significantly minimizing oil loss during shifting which is especially crucial in pilot control circuits. The valve's unique construction allows for port 3 to serve as the inlet and port 1 as the tank, supporting reverse flow albeit with non-guaranteed performance consistency. With a robust design that includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), this valve ensures reliable operation under demanding conditions. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The DNCALCN4E12V employs EPDM seals specifically for systems using phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. This model also features a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if the coil remains energized for extended periods. It supports a variety of coil termination and voltage options, including configurations with surge protection. Its magnetic design delivers high efficiency and strong spool actuating force per Watt expended, ensuring dependable valve shifting. Additional technical specifications include an 8 gpm (30 L/min) capacity, rapid response times typical at 50 ms, and maximum switching frequencies of up to 15,000 cycles per hour. The DNCALCN4E12V also incorporates Sun's floating style construction which reduces risks of internal parts binding due to installation issues or cavity/cartridge machining variations. This versatile cartridge valve is ideal for applications requiring reliable performance and precise fluid control in hydraulic systems.
