The Sun Hydraulics DMDAMBN924 (DMDAMBN924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and precise control in hydraulic systems. Featuring a fatigue rating of 5000 psi (350 bar), it ensures reliable operation under high-pressure conditions. The valve's spools B and R maintain a closed transition between two positions, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes manual override options with the D or L control, featuring a detent mechanism designed for temporary actuation and offering a mechanical life expectancy of approximately 7,000 cycles. The valve is compatible with EPDM seals for systems using phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The DMDAMBN924 employs a wet armature design where the working fluid surrounds the armature, which can influence fluid integrity if exposed to prolonged heat from an energized coil. This model also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum switching frequency of 15,000 cycles per hour. The manual override requires minimal force and has a stroke length suitable for precise control adjustments.
