The Sun Hydraulics DNCADLN912 (DNCADLN912) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. With a capacity of up to 8 gallons per minute and capable of operating at pressures up to 5000 psi, this model ensures robust performance in demanding applications. The valve's design allows for reverse flow; however, optimal performance under such conditions is not guaranteed. It incorporates a fatigue-rated solenoid tube assembly suitable for service up to 350 bar, making it highly durable under cyclic loading conditions. The DNCADLN912 operates without requiring minimum hydraulic pressure, enhancing its utility in various system configurations. Special attention is given to the wet armature design where the working fluid surrounds the armature. This setup can affect fluid integrity if exposed to heat for prolonged periods, particularly with water-glycol mixtures that may degrade and form varnishes impacting cartridge functionality. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended. These seals must not be exposed to petroleum-based fluids as they could cause damage. The solenoid\u2019s efficient magnetic design and high spool actuating force per watt expended ensure reliable valve actuation and shifting. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, multiple coil connector options offering up to IP69K protection, and optional weatherized coils for enhanced environmental shielding. The construction incorporates Sun\u2019s floating style to reduce internal part binding due to installation torque or cavity/cartridge machining variations. Overall, the Sun Hydraulics DNCADLN912 offers a versatile solution for directing hydraulic flow efficiently in complex systems requiring precise control and reliability under high-pressure conditions.
