The Sun Hydraulics DMDAMAV628 (DMDAMAV628) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is well-suited for applications requiring robust performance as it operates without the need for minimum hydraulic pressure. The unit features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure systems. The DMDAMAV628 incorporates a closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly in pilot control setups where capacity is less critical. It also includes a manual override with a detent mechanism designed for temporary actuation, boasting a mechanical life expectancy of about 7,000 cycles. This model uses EPDM seals optimized for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which could be sensitive to prolonged energization due to potential heat build-up affecting fluid integrity. For versatility in system design, the valve\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction features Sun's floating style which minimizes internal part binding risks caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and swift typical response times of 50 ms, this valve ensures efficient operation across various hydraulic applications.
