The Sun Hydraulics DNCALJN211 (DNCALJN211) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This model features a closed transition between positions to minimize oil loss during shifting, an essential feature for maintaining efficiency in pilot control circuits. With a capacity of 8 gpm/30 L/min and the ability to handle maximum operating pressures up to 5000 psi/350 bar, the DNCALJN211 is robust and versatile for various hydraulic applications. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long-term performance. It operates without needing minimum hydraulic pressure, making it suitable for a wide range of operational environments. The DNCALJN211 uses EPDM seals specifically for systems with phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids which can cause damage. This model incorporates a wet armature design where the working fluid surrounds the armature\u2014this aspect should be considered when the coil is energized continuously as it impacts fluid integrity over time. The DNCALJN211 offers various coil termination and voltage options, including models with surge protection to meet different installation requirements. Its coils are interchangeable with other Sun Series 1 solenoid products and feature IP69K rated connector options for enhanced environmental protection. Sun Hydraulics has engineered this valve with their floating style construction to reduce internal parts binding due to installation torque or cavity/cartridge machining variations. This design consideration enhances reliability and performance consistency across different applications. With its rapid response time of approximately 50 ms and a switching frequency capable of handling up to 15,000 cycles per hour, the DNCALJN211 is an efficient solution for dynamic systems requiring precise control and frequent switching actions.
