VB7000 series flange electric two-way valve for air conditioning, heat and ventilation, heat treatment plant for industrial and working-fluid control industry. Two-and three links in the form 
 Product Features: 
 1, actuator selection of cast aluminum bracket and the plastic shell, small size, light weight. 
 2, the selection of permanent magnet synchronous motors, hysteresis clutch with institutions with a reliable, self-protection function. 
 3, for a variety of control signals: incremental (floating point), voltage (0 ~ 10V), current (4 ~ 20mA). 
 4, 0 ~ 10V or 4 ~ 20mA feedback signal (optional). 
 5, the transmission gear metal gear, greatly improving the life of the drive. 
 6, low power consumption, power output, and noise. 
 7, the body cast copper, cast iron, ductile iron, a variety of materials to choose from to suit the requirements of different medium and temperature. 
 8, the valve body threaded connections and flanges connecting the two, easy to install. 
 9, the body structure: two-way valve (single seat), two-pass balance valve (balanced).
