The Sun Hydraulics DMDADBN636 (DMDADBN636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly efficient and versatile for use in systems where consistent performance is critical. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DMDADBN636 model incorporates advanced design elements such as 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. Additionally, the manual override mechanism included in models with D or L control is specifically designed for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. This valve also utilizes EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. A notable feature of the DMDADBN636 is its wet armature design which involves the working fluid surrounding the armature\u2014important to consider as prolonged coil energization can lead to fluid degradation. For enhanced compatibility and ease of maintenance, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction employs Sun's floating style approach to minimize internal parts binding due to potential installation torque excesses or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, this valve stands out as an optimal solution for efficient directional control in hydraulic systems.
