The Sun Hydraulics DMDADNV2E12V (DMDADNV2E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its reliability and responsiveness across various applications. With a robust design featuring a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar), it ensures durable performance even under demanding conditions. The valve's manual override options include detent mechanisms (D or L control) primarily intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. The spools in models B and R maintain a closed transition between two positions, optimizing performance by ensuring faster and more consistent response times at the cost of lower flow capacity. This characteristic makes the valve particularly suitable for pilot control applications where flow capacity is less critical. Equipped with EPDM seals, the DMDADNV2E12V is compatible with phosphate ester fluids but should avoid exposure to petroleum-based fluids to prevent seal damage. Its wet armature design allows the working fluid to cool the armature, although prolonged energization could affect fluid integrity in certain conditions. For versatility in installation and maintenance, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This valve also incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With features like a maximum operating pressure of 5000 psi, a typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, the DMDADNV2E12V is an excellent choice for advanced hydraulic systems requiring reliable and efficient directional control.
