The Sun Hydraulics DMDAXAN824 (DMDAXAN824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates with no minimum hydraulic pressure required, ensuring reliable performance across a range of applications. The valve features a fatigue rating for up to 5000 psi (350 bar), making it suitable for high-pressure environments. The design includes B and R closed spools in the transition between positions to enhance performance limits at the cost of lower capacity. However, when used as pilot controls where capacity is less critical, this feature allows for faster and more consistent response times. The manual override in models equipped with D or L control is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This valve utilizes EPDM seals specifically configured for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, the wet armature design means the working fluid surrounds the armature which can be a consideration if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures. Interchangeable coils with other Sun Series 1 solenoid products add versatility to this model, allowing coils to be mounted in either direction on the tube. The construction incorporates Sun's floating style which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and typical response time of 50 ms, this valve ensures efficient operation. Its switching frequency can reach up to 15,000 cycles per hour, highlighting its capability for rigorous use. Additionally, it supports manual override with minimal force requirements and precise control strokes, making adjustments both straightforward and effective.
