The Sun Hydraulics DMDAMRN712N (DMDAMRN712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its reliability and versatility in various applications. The model features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial uses. The valve's spools, designated B and R, maintain a closed position during transitions to ensure higher performance limits at the cost of reduced capacity. This characteristic is particularly beneficial in pilot control applications where rapid and consistent response times are crucial, rather than flow capacity. Additionally, the DMDAMRN712N incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Further enhancing its utility, the valve boasts interchangeable coils within Sun's Series 1 solenoid products and can be mounted in either direction on the tube. It also utilizes a wet armature design where the working fluid surrounds the armature which could be significant if the coil remains energized over extended periods. The manual override feature is equipped with a detent mechanism intended for temporary actuation with an expected mechanical life of about 7,000 cycles. The construction of this model includes Sun's floating style design which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With features like a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDAMRN712N is engineered for both efficiency and longevity in demanding settings.
