Ball valves for higher temperature FB39

Ball valves for higher temperature

PURPOSE AND SPHERE OF APPLICATION

Ball valves Termo are the modification of all series of Fobos ball valves. Ball valves Termo are intended to be fitted as stop/shutoff valves in the process lines (including steam pipeline) of rubber and tire plants, chemical and oil-refining plants, at pulp-and-paper mills 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

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.
