The Sun Hydraulics DNCAMAV612N (DNCAMAV612N) is a solenoid-operated, 4-way, 2-position cartridge valve designed as a direct-acting, balanced spool directional valve. This model features a closed transition between positions, effectively minimizing oil loss during shifting\u2014a crucial factor in pilot control circuits. The valve's optimal capacity is achieved with port 3 as the inlet and port 1 as the tank; however, reverse flow is not recommended due to potential performance discrepancies. It boasts a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability in high-pressure applications. Notably, this valve operates without requiring minimum hydraulic pressure and employs EPDM seals suitable for phosphate ester fluid systems while avoiding petroleum-based fluids to prevent seal damage. The DNCAMAV612N utilizes a wet armature design where the working fluid surrounds the armature, which can be affected by coil-generated heat during prolonged energization periods. This design consideration is essential for fluids like water-glycol mixtures that may degrade over time at elevated temperatures. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring reliable valve shifting. Compatibility with various coil termination and voltage options\u2014some offering IP69K ratings\u2014adds versatility to its application range. Incorporating Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. With a cavity of T31A and Series 1 classification, it supports capacities up to 8 gpm (30 L/min), with a typical response time of 50 ms and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The DNCAMAV612N is designed for frequent switching operations up to 15,000 cycles per hour and includes features such as manual override capabilities with specific force requirements and stroke dimensions.
