The Sun Hydraulics DMDADNV212N (DMDADNV212N) is a solenoid-operated, 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Engineered for high-performance applications, this valve features a fatigue-rated solenoid tube assembly designed to withstand pressures up to 5000 psi (350 bar), making it suitable for rigorous hydraulic operations. The transition between the two positions of spools B and R is closed, enhancing performance by ensuring faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, thus facilitating its use in various fluid power systems. It includes manual override options with a detent mechanism intended for temporary actuation; these are available in D, L, and T manual control assemblies which boast a mechanical life expectancy of approximately 7,000 cycles. Special attention needs to be given to the EPDM seal configurations which are compatible only with phosphate ester fluids; exposure to petroleum-based substances can cause damage. The valve's wet armature design helps in heat management but requires consideration regarding the type of fluid used due to potential breakdowns at elevated temperatures. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction incorporates Sun\u2019s floating style design which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. Noteworthy specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure sustainability at 5000 psi (350 bar). Its design also supports switching frequencies up to 15,000 cycles per hour and features manual override requirements that ensure operational control under varying pressures.
