The Sun Hydraulics DMDAMPN212N (DMDAMPN212N) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), suitable for demanding applications. The valve operates with no minimum hydraulic pressure required, enhancing its versatility in various system configurations. Equipped with spools B and R, the DMDAMPN212N ensures closed transitions between positions, optimizing response times and consistency in pilot control applications where capacity is less critical. The manual override feature in models with D or L control includes a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. This model incorporates EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature which could be a consideration if the coil remains energized over extended periods since some fluids may degrade under sustained heat. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, Sun's floating style construction minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With a flow capacity of 12 gpm (45 L/min) and swift typical response time of 50 ms, along with robust switching frequency capabilities up to 15,000 cycles/hr, this valve is engineered for reliability and efficient operation across various hydraulic applications.
