Butterfly valves are widespread among diverse industries and applications such as pharmaceutical, chemical and oil, food, water supply, wastewater treatment, fire protection, gas supply, fuel handling. These valves are available in very large sizes and are suitable for handling slurries, and liquids with relatively large amounts of solids at low pressures.

Valve Location

Butterfly valves should be installed if possible a minimum of 6 pipe diameters from other line elements, i.e. elbows, pumps, valves, etc. Sometimes this is not feasible, but it is important to achieve as much distance as possible.
Where the Butterfly valve is connected to a check valve or pump, keep enough space between them to ensure the disc does not interfere with the adjacent equipment.

As a rule of thumb, Butterfly valves be installed with the stem in the vertical position with the actuator mounted vertically directly above it, however, there are some applications where the stem should be horizontal.
