The Sun Hydraulics DMDADPN212N (DMDADPN212N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable control with its fatigue-rated solenoid tube assembly for service pressures up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The DMDADPN212N operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system conditions. It includes manual overrides (D, L, T control types) with a mechanical life expectancy of about 7,000 cycles. These are intended primarily for temporary actuation. It's important to note that cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based substances can damage these seals. This model also employs a wet armature design where the working fluid surrounds the armature which is exposed to heat when the coil is energized for extended periods. This design consideration is crucial as certain fluids may degrade under prolonged heat exposure. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. With a maximum operating capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDADPN212N is engineered to handle demanding switching operations up to 15,000 cycles per hour efficiently. The valve also incorporates Sun's floating style construction which minimizes internal parts binding\u2014a result of excessive installation torque or variations in cavity/cartridge machining\u2014ensuring long-term reliability and performance stability in your hydraulic systems.
