The Sun Hydraulics DNCAMAN912 (DNCAMAN912) is a solenoid-operated, 4-way, 2-position cartridge valve designed as a direct-acting, balanced spool directional valve. It features a closed transition between positions to minimize oil loss during shifting, which is crucial for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is not recommended due to potential performance issues. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring robust performance under high pressure. This direct-actuated valve requires no minimum hydraulic pressure for operation and employs EPDM seals suitable for phosphate ester fluid systems, although they should not be exposed to petroleum-based fluids to avoid damage. The DNCAMAN912 utilizes a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil. This feature requires consideration of fluid types, as some may degrade over time with prolonged coil energization. A variety of coil termination and voltage options are available, including configurations with surge protection. The high-efficiency solenoid design offers significant spool actuating force per watt, enhancing reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model incorporates Sun's floating style construction to reduce internal part binding caused by excessive installation torque or machining variations. It fits into cavity T-31A and has an operational capacity of 8 gpm (30 L/min). The maximum operating pressure is set at 5000 psi (350 bar), with typical response times of around 50 ms and minimal leakage at specified conditions. Additional features include manual override capabilities and compatibility with various environmental protection kits for enhanced durability in demanding applications.
