The Sun Hydraulics DNCADWN4E12V (DNCADWN4E12V) is a high-performance, solenoid-operated directional valve, designed for precise hydraulic control. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with closed transition between positions, significantly minimizing oil loss during shifting. This characteristic is especially beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. Engineered for robust performance, the DNCADWN4E12V operates efficiently with a maximum capacity of 8 gpm/30 L/min and can handle pressures up to 5000 psi/350 bar. The valve is uniquely constructed with a wet armature design allowing the working fluid to surround the armature; however, it\u2019s important to monitor fluid integrity as prolonged exposure to heat can lead to breakdown and varnish formation, particularly with water-glycol mixtures. This model incorporates Sun's floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. Its solenoid assembly is fatigue rated for high-pressure service up to 5000 psi/350 bar, ensuring reliable operation under demanding conditions. Additionally, the DNCADWN4E12V offers various coil termination and voltage options including models with surge protection and weatherized kits for enhanced environmental resilience. The valve's rapid response time of approximately 50 ms and its capability of up to 15,000 switching cycles per hour make it an excellent choice for applications requiring frequent and precise operation. The manual override feature requires minimal force, enhancing ease of use under different pressure settings. With interchangeable coils compatible with other Sun Series 1 solenoid products and multiple sealing options available (notably EPDM seals for phosphate ester fluids), this valve ensures versatile application across diverse hydraulic systems while maintaining superior performance and reliability.
