Improved valve on basis of marketing research and primary hemisphere valve.
Executive mechanism installed with 90° rotary electric executor facilitates operation of users.
Realizes remote automatic operation and extends scope of use of semi-spherical valve.
Especially in some odious environment manual operation or normally open actions are not possible, it is really an innovation that dual eccentric semi-spherical valve is equipped with electric executive mechanism under automatic computer operation
Case of explosion- and fire-resistant measures are required for electric control device, please state class of protection and detailed instruction
Valve is featured with easy opening, removing fouling factor after closing, nice sealing performance and other conventional advantages of semi-spherical valves
Anti-abrasive and -corrosive
