The Sun Hydraulics DMDADBV512 (DMDADBV512) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. Featuring a direct-acting, balanced spool directional control, this valve ensures precise operation with its closed spool transitions between positions B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. Constructed with durability in mind, the DMDADBV512 can withstand up to 5000 psi (350 bar), and its solenoid tube assembly is fatigue rated for the same pressure. It incorporates Sun's floating style construction which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. This model also features interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. The manual override mechanism equipped on models with D or L control is designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve means that the working fluid surrounds the armature which could be susceptible to heat if the coil remains energized for extended periods. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 3000 psi set at about 5 in\u00b3/min. The valve also supports a switching frequency up to 15,000 cycles per hour and requires manual override force of about 5 lbs at 1000 psi for port operation. This model weighs approximately 0.60 lb (0.30 kg) and has installation torque requirements between 30-35 lbf-ft (41-47 Nm).
