The Sun Hydraulics DNCALJN912N (DNCALJN912N) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical advantage in pilot control circuits. With a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, it ensures reliable operation even though reverse flow is possible but not recommended for optimal performance. Engineered to handle a maximum operating pressure of 5000 psi/350 bar, the DNCALJN912N valve is fatigue rated for demanding applications. Its solenoid tube assembly requires no minimum hydraulic pressure for operation, making it versatile across various hydraulic setups. The valve is equipped with EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. A notable feature of this model is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods as it affects fluid integrity due to heat exposure. The DNCALJN912N offers an array of coil termination and voltage options, enhancing its adaptability to different system requirements while maintaining high efficiency and effective spool actuating force per Watt expended. Additional features include interchangeable coils with other Sun Series 1 solenoid products and multiple connector options rated up to IP69K for superior environmental protection. The innovative Sun floating style construction also reduces internal parts binding by accommodating installation torque and cavity/cartridge machining variations. With a swift response time of approximately 50 ms and capability for up to 15,000 switching cycles per hour, this valve stands out as a robust solution for directional control in hydraulic systems.
