 Electrically actuated cutoff ball valves
FB39
(MBOV electrical actuator)
PURPOSE AND SPHERE OF APPLICATION
Electrically actuated cutoff ball valves FB 39 with MBOV electrical actuator are intended to be fitted as automated devices on pipelines, where valve fast closing is required because of the process conditions, and as cutoff valves in the process lines using fluid, gaseous, and corrosive working media. Distinctive features of these valves are reliability and speed. |

VALVE DESIGN
| | The through valve consists of the body (1), and the caps (2), bolted together by stud bolts (12). The ball seats (5) within the rings (6) press the ball (3). The blowout proof valve stem (4) is sealed with two gaskets (8) and (9) compressed by the thrust washer (10) and the stem nut (11). The working medium can be admitted to any of the caps. The valve can be mounted on the pipeline in any attitude position required. The valve is supplied with the electrical actuator MBOB-63/1-0.25. The actuators are delivered by «Pribor» JSC and supplied with the control box БУП МБО-63
