The Sun Hydraulics DMDADBV211 (DMDADBV211) 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 operational efficiency, featuring a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. The valve exhibits minimal leakage with a maximum rate of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), ensuring efficient performance under high-pressure conditions. A key feature of the DMDADBV211 model is its closed transition between Spools B and R, which enhances performance limits while sacrificing some capacity. This makes it particularly suitable for applications as pilot controls where capacity is less critical but fast and consistent response times are essential. The valve operates effectively without minimum hydraulic pressure and incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For ease of maintenance and versatility, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The design also includes Sun\u2019s floating style construction which minimizes internal parts binding due to variations in installation torque or cavity/cartridge machining. The DMDADBV211 supports a flow capacity up to 12 gpm (45 L/min) and features a typical response time of 50 ms. Manual override options equipped with the D or L control offer temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model\u2019s wet armature design allows the working fluid to cool the armature, although prolonged energization should be monitored as it may degrade certain fluid types over time.
