The Sun Hydraulics DMDAMNV212N (DMDAMNV212N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to operate seamlessly under high-pressure conditions up to 5000 psi (350 bar), making it suitable for a wide range of hydraulic applications. The unique feature of this model includes its closed transition between spools B and R, which enhances performance by providing faster and more consistent response times especially useful in pilot control operations where capacity is less critical. The DMDAMNV212N valve operates without requiring a minimum hydraulic pressure, contributing to its versatility in various system configurations. It incorporates a wet armature design allowing the working fluid to surround the armature; however, care must be taken as prolonged energization can lead to fluid degradation under heat. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended, while exposure to petroleum-based fluids should be avoided to prevent seal damage. This model also features interchangeable coils with other Sun Series 1 solenoid products for enhanced adaptability and maintenance ease. The construction employs Sun's floating style which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With a mechanical life expectancy of approximately 7,000 cycles for models equipped with manual control assemblies (D, L, and T), it ensures durability and reliability in demanding environments. Additional specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The DMDAMNV212N also supports a manual override feature requiring minimal force, thus enhancing operational flexibility. This robust valve design is ideal for applications requiring precise control and high reliability in hydraulic systems.
