The lifting lug butterfly valve is also widely used in: steam, air, gas, ammonia, oil, water, brine, alkali, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in chemical, petrochemical, smelting, pharmaceutical, food and other industries On the pipeline as a regulating and shut-off device.
The lug butterfly valve is similar in design to a three-piece ball valve in that one end of the line can be removed without affecting the other side. This can be achieved by using threaded inserts, flanges, and two sets of lugs (bolts) that do not use nuts, since each flange has its own bolt. It is also important to note that the entire system does not need to be shut down when cleaning, inspecting, servicing or replacing lug butterfly valves (requires wafer style butterfly valves).
