Formen fully welded ball valves are widely used in various pipeline systems such as urban gas, urban heating, petrochemical, shipbuilding, steel industry, pressure regulating stations, and power plants.
The under-ground stem extended fully welded ball valve is designed as under-ground installation, no need the large valve wells, which reduces the project cost and improve the efficiency. At the same time, the valve can be operated on the ground, which keeping the operation safety.
Anti- Blowout Stem design
Formen ball valves stem is made separately from the ball. The lower end of the stem is designed with an intergral shoulder to be blowout-proof.
Anti-static Device
Its a standard feature of antistatic device for Formen ball valve. A spring-loaded pin assures the electrical continuity between the ball, stem and body to avoid sparking during the turning of the stem to open and closed the valve.
Emergency sealant injection plug
As for 6inch and larger Formen trunnion mounted ball valves, sealant injection plug will be installed on both the stem and seats. When the sealing materials are damaged, the leakage can be prevented by the sealant injected in to these plugs.
DELTA RING seat design (As optional)
Formen fully welded ball valves seat primary sealing is O-ring Viton, the second sealing is elastomer delta ring, double sealing to obtain zero leakage easily.
