The Sun Hydraulics DMDADBV628 (DMDADBV628) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is capable of handling a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for demanding environments and high-pressure applications. The DMDADBV628 operates without the need for minimum hydraulic pressure, enhancing its versatility in various system configurations. Its wet armature design allows the working fluid to surround the armature, which is crucial in applications where the coil may be energized for extended periods. However, this design requires careful consideration of the fluid type used, as some fluids may degrade under prolonged exposure to heat. This model incorporates Sun's floating style construction, which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. The valve offers rapid response times with typical actuation speeds around 50 ms and supports switching frequencies up to 15,000 cycles per hour. Spools B and R maintain closed positions during transitions, optimizing performance by ensuring faster and more consistent responses. For maintenance and customization, it features interchangeable coils compatible with other Sun Series 1 solenoid products and can be configured with EPDM seals for use with specific fluid types like phosphate esters. The manual override option provided includes a detent mechanism designed primarily for temporary actuation. In summary, the Sun Hydraulics DMDADBV628 valve is engineered for precision control in hydraulic systems requiring reliable performance under high pressure and variable conditions. Its robust construction and thoughtful design elements make it suitable for a wide range of industrial applications.
