The Sun Hydraulics DMDADBV928 (DMDADBV928) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). The valve features a robust design with spools B and R that are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDADBV928 incorporates a wet armature design that allows the working fluid to surround the armature. This design helps in heat management when the coil is energized for extended periods but requires careful consideration of fluid selection as some fluids may degrade under prolonged exposure to heat. It's important to note that cartridges configured with EPDM seals should only be used with phosphate ester fluids, as exposure to petroleum-based fluids can damage these seals. This model also boasts interchangeable coils with other Sun Series 1 solenoid products, enhancing its versatility and ease of maintenance. The manual override feature included in this model has a mechanical life expectancy of approximately 7,000 cycles and is intended for temporary actuation only. Furthermore, the valve utilizes Sun's floating style construction which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. With its quick response time (typically around 50 ms), minimal valve leakage at high pressures, and a manual override system requiring minimal force, the DMDADBV928 offers reliability and efficiency for demanding hydraulic applications.
