The Sun Hydraulics DNCADZN828 (DNCADZN828) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. This valve is specifically designed for applications requiring closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining efficiency in pilot control circuits. With a capacity of 8 gpm/30 L/min and an impressive maximum operating pressure of 5000 psi/350 bar, the DNCADZN828 offers robust performance for various hydraulic systems. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long-term reliability. It operates without requiring a minimum hydraulic pressure, making it versatile across different operational conditions. The DNCADZN828 uses EPDM seals suited to systems with phosphate ester fluids; however, these seals are sensitive to petroleum-based fluids which can cause damage. A standout feature of this model is its wet armature design where the working fluid surrounds the armature. While advantageous in some scenarios, prolonged exposure to heat when the coil is energized can degrade certain fluid types like water-glycol mixtures. The valve also boasts a variety of coil termination and voltage options that cater to different environmental needs with options up to IP69K protection rating. Sun Hydraulics has equipped the DNCADZN828 with interchangeable coils compatible with other Series 1 solenoid products and features such as manual override capabilities and switching frequency up to 15000 cycles/hr. Additionally, the floating style construction of this valve helps minimize internal parts binding due to installation torque or machining variances in cavity/cartridge configurations. Overall, the Sun Hydraulics DNCADZN828 offers advanced control for hydraulic systems demanding precise operation under varying conditions and pressures.
