The Sun Hydraulics DNCALJN712 (DNCALJN712) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve that excels in delivering reliable and efficient directional control in hydraulic systems. This direct-acting, balanced spool valve is designed with a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for maintaining the integrity and efficiency of pilot control circuits. The DNCALJN712 operates with a valve capacity based on port 3 as the inlet and port 1 as the tank, though it allows reverse flow under certain conditions. Its robust solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability even under demanding conditions. Notably, this valve does not require a minimum hydraulic pressure to function effectively, making it versatile across various applications. Equipped with EPDM seals, the DNCALJN712 is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of this model means that the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods. This model also features a variety of coil termination and voltage options to suit different operational requirements and environments. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate system design variations. Additionally, its unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended. For installation flexibility and reliability, the DNCALJN712 incorporates Sun's floating style construction which helps prevent internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With specifications like an 8 gpm (30 L/min) capacity and fast response times typical at 50 ms, this valve is an excellent choice for systems requiring precise control and rapid switching capabilities.
