The Sun Hydraulics DMDAMNV212 (DMDAMNV212) is a solenoid-operated 3-way, 2-position cartridge valve designed for precision and reliability in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, including a solenoid tube assembly rated for fatigue at 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, making it versatile in various operating conditions. The DMDAMNV212 comes equipped with an optional manual override (D, L, or T control options), designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It also includes EPDM seals suitable for phosphate ester fluids but must avoid exposure to petroleum-based substances to prevent seal damage. The wet armature design of the valve allows the working fluid to surround the armature which can be a consideration during extended periods of coil energization due to potential fluid degradation at high temperatures. This valve is compatible with other Sun Series 1 solenoid products concerning coil interchangeability and can be mounted in either direction on the tube. Additional specifications include a flow capacity of up to 12 gpm (45 L/min), a maximum operating pressure of 5000 psi (350 bar), and typical response times of around 50 ms. It supports switching frequencies up to 15,000 cycles per hour and incorporates Sun's floating style construction that minimizes internal parts binding due to installation variances. The manual override requires a force of approximately 5 lbs at 1000 psi per port and has a stroke length of .10 inches (2.5 mm). The overall model weight is modest at .60 lb (0.30 kg).
