The Sun Hydraulics DNCAMTV512 (DNCAMTV512) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This directional valve features a closed transition between positions, significantly reducing oil loss during shifting\u2014a crucial advantage in 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 possible but not recommended due to potential performance degradation. Designed for robust service, the solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve operates without needing a minimum hydraulic pressure and uses EPDM seals suitable for phosphate ester fluid systems, while exposure to petroleum-based fluids can damage these seals. The DNCAMTV512 incorporates a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil\u2014an essential consideration for prolonged coil energization. Certain fluids like water-glycol mixtures may degrade at these temperatures over time, affecting cartridge function. The solenoid's magnetic design enhances efficiency by delivering high spool actuating force per watt expended, ensuring reliable shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model offers various coil termination and voltage options with surge protection capabilities and weatherized variations for environmental resilience. It includes features such as a manual override stroke of .10 inches (2.5 mm) requiring a force of 5 lbs/1000 psi (33 N/100 bar at Port 1), a response time of approximately 50 ms, and can handle switching frequencies up to 15,000 cycles per hour. The valve also incorporates Sun's floating style construction to minimize internal part binding due to installation torque or cavity machining variations.
