The Sun Hydraulics DMDAXRN212N (DMDAXRN212N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional design that ensures reliable operation without the need for minimum hydraulic pressure. The valve is particularly suitable for applications requiring rapid and consistent response times, thanks to its closed transition between Spools B and R which enhances performance at the cost of capacity\u2014ideal when used as pilot controls where capacity is less critical. This model boasts a fatigue rating for up to 5000 psi (350 bar) service in its solenoid tube assembly, making it robust for demanding environments. The manual override options available with the D or L control are designed for temporary actuation, supported by a detent mechanism that has a mechanical life expectancy of around 7,000 cycles. Additionally, the valve incorporates EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. The DMDAXRN212N utilizes a wet armature design allowing the working fluid to surround the armature which can be significant if the coil remains energized over extended periods. This model also features interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. It incorporates Sun\u2019s floating style construction to reduce internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With its quick response time typically around 50 ms and a maximum operating pressure of 5000 psi (350 bar), along with other specifications like a flow capacity of up to 12 gpm (45 L/min), this valve is engineered to meet rigorous industrial demands while ensuring precision and durability in operation.
