The Sun Hydraulics DMDAMNV828 (DMDAMNV828) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and efficient operation. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The valve offers closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially when used as pilot controls where capacity is less critical. The DMDAMNV828 operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power contexts. For manual override situations, models equipped with D or L control include a detent mechanism designed for temporary actuation with an estimated mechanical life of around 7,000 cycles. This model utilizes EPDM seals specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature which may be a consideration 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 to this valve, allowing for easy maintenance and replacement. The design also incorporates Sun\u2019s floating style construction which minimizes internal parts binding from excessive installation torque or cavity/cartridge machining variations. With specifications including a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar), the Sun Hydraulics DMDAMNV828 provides reliable and effective control for hydraulic systems in various applications.
