The Sun Hydraulics DNCADJN211 (DNCADJN211) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve, featuring a direct-acting, balanced spool with closed transition between positions. This design significantly minimizes oil loss when shifting, which is particularly crucial in pilot control circuits. The valve has been engineered to handle a flow capacity of 8 gpm/30 L/min with port 3 as the inlet and port 1 as the tank outlet. While reverse flow is possible through this configuration, it is not recommended as performance consistency cannot be assured. The DNCADJN211 operates without requiring a minimum hydraulic pressure and its solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar). It includes EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The valve\u2019s wet armature design allows the working fluid to surround the armature which helps in managing heat generated by the coil during prolonged energization. This factor needs consideration especially when using water-glycol mixtures that may degrade under high temperatures. Additionally, it offers various coil termination and voltage options including models with surge protection. The coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. Options for enhanced environmental protection through weatherized coils and kits are also available. This model incorporates Sun\u2019s floating style construction which reduces risks of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a robust response time of approximately 50 ms and capable of handling up to 15,000 switching cycles per hour, the DNCADJN211 proves ideal for demanding applications requiring reliable and precise control over hydraulic flow directions under varied pressure settings.
