The Sun Hydraulics DNCAMBV712N (DNCAMBV712N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional mechanism. Designed for efficient fluid control, this valve excels in minimizing oil loss during transitions due to its closed transition design, making it particularly beneficial for pilot control circuits. The valve's optimal performance is achieved with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly is engineered to withstand fatigue at pressures up to 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. This direct-actuated valve operates without a minimum hydraulic pressure requirement and incorporates EPDM seals suitable for phosphate ester fluids, though these seals should not be exposed to petroleum-based substances. The DNCAMBV712N utilizes a wet armature design where the working fluid cools the armature but may degrade over time if exposed to high temperatures from prolonged coil energization. A variety of coil termination and voltage options are available, including configurations with surge protection. The high-efficiency solenoid design results in significant actuating force per watt of energy used, facilitating reliable shifting of the valve spool. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bi-directionally on the tube. The product offers coil connector options with ratings up to IP69K for enhanced environmental protection. This model features Sun's floating style construction which reduces potential binding of internal parts due to installation torque or machining variations in cavity/cartridge applications. With a capacity of 8 gpm (30 L/min) and a typical response time of 50 ms, this valve is robustly designed for frequent switching cycles up to 15,000 per hour while maintaining low leakage rates at maximum operating conditions.
