The Sun Hydraulics DMDADAN636 (DMDADAN636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous industrial applications. This direct-acting, balanced spool directional valve is notable for its robust construction and efficient operation. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for high-pressure environments. The valve's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDADAN636 operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power circuits. It offers manual override options with a mechanical life expectancy of approximately 7,000 cycles, ensuring reliable manual operation when needed. The valve uses EPDM seals configured specifically for systems utilizing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Additionally, the wet armature design of the DMDADAN636 helps in maintaining the armature's efficiency but requires consideration of the fluid type used as prolonged exposure to heat can degrade certain fluids. The interchangeable coils with other Sun Series 1 solenoid products add versatility to this model, allowing for easier maintenance and replacement. Its floating style construction minimizes internal parts binding, thus enhancing the durability and reliability of the installation even under varying torque and machining conditions. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient flow control in hydraulic systems. Its compact size and light weight (.60 lb or 0.30 kg) make it an excellent choice for space-constrained applications requiring precise control over fluid direction and pressure.
