The Sun Hydraulics DMDAMPN928 (DMDAMPN928) 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 solenoid tube assembly that is fatigue rated for demanding 5000 psi (350 bar) service conditions, ensuring reliable operation under high-pressure scenarios. The unique design of spools B and R, which remain closed during the transition between positions, enhances performance by offering faster and more consistent response times, especially suitable for applications where capacity is not a critical factor. This model operates efficiently without the need for minimum hydraulic pressure, facilitating its use in a variety of fluid power applications. The valve is also equipped with manual override options including D or L control types; however, these are intended primarily for temporary actuation with a mechanical life expectancy around 7,000 cycles. Additionally, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; however, they must avoid exposure to petroleum-based substances to prevent seal damage. The DMDAMPN928 incorporates advanced wet armature design allowing the working fluid to surround the armature which can be critical when considering the heat generated by long periods of coil energization. This product supports interchangeability with other Sun Series 1 solenoid products and features floating style construction to minimize internal binding caused by installation torque or machining variations. With specifications like a maximum flow capacity of 12 gpm (45 L/min), rapid typical response time of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), this valve stands out as an efficient solution in hydraulic systems requiring precise control and reliability.
