The Sun Hydraulics DMDAMBN928 (DMDAMBN928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve features a robust design, including a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). It is specifically engineered to ensure reliable operation with no minimum hydraulic pressure required for functionality. The DMDAMBN928 offers precise control with closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The manual override options available with the D or L control include a detent mechanism intended for temporary actuation, supporting up to approximately 7,000 cycles. For compatibility with different fluid types, cartridges equipped with EPDM seals are intended for use with phosphate ester fluids; however, they must not be exposed to petroleum-based substances which could degrade the seals. Additionally, this model uses a wet armature design where the working fluid surrounds the armature\u2014important to consider if the coil remains energized over extended periods due to potential breakdowns in certain fluids like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility in maintenance and replacement processes. The construction incorporates Sun's floating style to minimize internal parts binding caused by installation torque or cavity/cartridge machining variations. Specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). This makes the DMDAMBN928 an ideal choice for applications requiring robust and precise hydraulic control in various configurations and operational conditions.
