The Sun Hydraulics DNCAMZV211 (DNCAMZV211) is a solenoid-operated, 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. It features a closed transition between positions, which significantly minimizes oil loss during shifting, making it particularly beneficial for pilot control circuits. This valve is engineered with port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), allowing robust service conditions. Notably, this valve does not require any minimum hydraulic pressure to operate due to its direct actuation design. The DNCAMZV211 incorporates EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to surround the armature and absorb heat from the coil, which could impact function if the coil remains energized for extended periods\u2014particularly with fluids like water-glycol mixtures that degrade at high temperatures. This model offers various coil termination and voltage options with or without surge protection and boasts a unique magnetic design that enhances solenoid efficiency by providing high spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The valve also features Sun's floating style construction to prevent internal parts from binding due to excessive installation torque or cavity/cartridge machining variations. It has a capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar).
