The Sun Hydraulics DMDATRN612 (DMDATRN612) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve's design ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. The DMDATRN612 operates without the need for minimum hydraulic pressure, thus facilitating direct actuation. Certain models come equipped with D or L control options, incorporating a detent mechanism in the manual override intended for temporary actuation only. With a mechanical life expectancy of approximately 7,000 cycles for the manual control assembly and interchangeable coils compatible with other Sun Series 1 solenoid products, this valve offers both versatility and durability. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature which may be susceptible to heat during prolonged coil energization. It\u2019s important to note that using EPDM seals restricts this model to systems utilizing phosphate ester fluids as exposure to petroleum-based substances can degrade these seals. Key specifications include a flow capacity of up to 12 gpm (45 L/min), quick response times typically around 50 ms, and maximum operational pressure limits maintained at 5000 psi. The valve also features Sun's floating style construction which minimizes internal parts binding from excessive installation torque or cavity-cartridge machining variations. This engineering consideration ensures reliable operation and ease of installation across various hydraulic applications.
