The Sun Hydraulics DMDADBV248 (DMDADBV248) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is specifically engineered for robust service with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The DMDADBV248 is characterized by its closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly when used as pilot controls where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes options for manual overrides with D, L, or T controls; however, these are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve's construction uses EPDM seals configured for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. A notable feature of the DMDADBV248 is its wet armature design which allows the working fluid to surround the armature. This design consideration is crucial when the coil remains energized over long periods as heat generation can affect certain types of hydraulic fluids. Additionally, the valve supports interchangeable coils from other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal parts binding due to installation variances or machining errors. With its compact dimensions and a weight of only 0.60 lb (0.30 kg), this valve supports up to 12 gpm (45 L/min) capacity and offers quick response times typically around 50 ms. It also features manual override capabilities requiring minimal force and allows up to 15,000 switching cycles per hour, ensuring reliable and efficient operation in various industrial applications.
