The Sun Hydraulics DMDAXAN812 (DMDAXAN812) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic fluid control. This direct-acting, balanced spool directional valve is engineered to be fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control setups where capacity is less critical. This model is designed with a wet armature configuration, where the working fluid surrounds the armature. This design consideration is crucial as it exposes the fluid to heat generated by the coil which can affect fluid properties over extended periods of energization. Users should note that EPDM seals are utilized in cartridges meant for systems with phosphate ester fluids; these seals are adversely affected by petroleum-based fluids. The DMDAXAN812 also includes interchangeable coils compatible with other Sun Series 1 solenoid products, offering flexibility in maintenance and upgrades. The manual override feature in this model has a mechanical life expectancy of approximately 7,000 cycles and requires minimal force for operation. Additionally, the floating style construction incorporated into the design minimizes internal parts binding which can occur due to excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient and reliable operation across various applications. It supports a switching frequency of up to 15,000 cycles per hour and maintains stringent leakage control standards under maximum operating pressure conditions. The compact dimensions and manual override features make it user-friendly and easy to integrate into existing hydraulic systems without extensive modifications.
