 Ball valves for higher temperature
Ser. Termo
FB39 PURPOSE AND SPHERE OF APPLICATION
Ball valves Termo are the modification of all series of Fobos ball valves. Intended to be fitted as stop/shutoff valves in the process lines (as well as steam pipeline) of rubber and tire plants, chemical and oil-refining plants, at pulp-and-paper milks and other production facilities using fluid, gaseous as well as corrosive working media. Distinctive feature of these valves is a special sealing withstanding temperature up to 270°С
| VALVE DESIGN
| The through ball valve consists of the valve body (1), the flange (4), and the cap (2) bolted together by stud bolts (15) and nuts (14). The blowout proof valve stem (5) is sealed with three gaskets (9) tighten the stem nut (13) and spring loaded by spring washers (12). The body ball (3) is sealed with the ball seats (8) and rubber rings (11). The cap-body joining is sealed with rubberized asbestos fabric joint gaskets (7). Valve shifting is performed by turning handle (6) through 90 degrees. The valve can be mounted on the pipeline in any attitude position required. The valve can be supplied with the valve-locking device. |
