The Sun Hydraulics DNCALLN612 (DNCALLN612) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is engineered for precise control with closed transition between positions, significantly minimizing oil loss during shifting\u2014an essential characteristic for pilot control circuits. Optimized for use with port 3 as the inlet and port 1 as the tank, it allows reverse flow but without guaranteed performance. The solenoid tube assembly of this model is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DNCALLN612 operates without requiring minimum hydraulic pressure due to its direct actuation design. It is compatible with systems using phosphate ester fluids when configured with EPDM seals; however, these seals are vulnerable to damage from petroleum-based fluids. The valve incorporates a wet armature design where the working fluid surrounds the armature, a consideration for applications involving prolonged coil energization as certain fluids may degrade into varnishes at higher temperatures. Offering versatility in electrical configurations, this model provides various coil termination and voltage options, some with surge protection. Its high-efficiency magnetic design enhances spool actuation force per watt expended, promoting reliable operation across its application range. Coils are interchangeable within Sun Series 1 products and can be mounted in either orientation on the tube. For environments demanding robust protection against elements, coil connector options are available with ratings up to IP69K. The valve's construction employs Sun\u2019s floating style to mitigate internal component binding due to excessive torque or machining variations. With a capacity of 8 gpm (30 L/min) and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), this model demonstrates efficient performance in hydraulic systems requiring dependable directional control solutions.
