When should you use a butterfly valve? Generally, to isolate or not a fluid, however, butterfly valves also allow to regulate the flow of the fluid, their operation is based on a blade or disk called a “butterfly” which, rotating on its axis, prevents or not, the passage of fluid. The great advantage of these valves is that they present a very low pressure drop when fully open since they hardly generate any loss of kinetic energy in the pipeline. They are used in neutral fluids, sludge, sanitary or corrosive depending on the material of the parts that compose it (body, disc, shaft and seat).
One of the advantages of butterfly valves is their low cost, therefore, one of the reasons that they are economical is their ability to operate large flows, thus avoiding the need to install smaller lines in the connection that present this.
Another reason is the fact that the valve body is not in direct contact with the passing fluid, therefore, in cases such as in the circulation of abrasive fluids, it makes it possible to use materials that are less expensive for the body. Another of its advantages is its ease of using maintenance and cleaning in them.
Butterfly valves have a great resistance to wear, however, they are not recommended for transporting liquids with suspension of solids since these would make it difficult to close the valve completely, compromising its tightness. Butterfly valves tend to open and close through their central axis, however, there are designs that use 2, 3 or up to 4 eccentricities in order to obtain perfect tightness in conditions where it is required to compensate for high pressure and extreme temperature.
The butterfly valves are coupled to the systems by means of wafer, lug, flange or clamp connections, the reduced space that they occupy thanks to their design compared to other control valves makes the butterfly valve a very versatile option.

The safety valve is an essential element of a fluid or gas system, it is responsible for relieving the pressure in the event of excess pressure due to a failure in the system, therefore, it ensures optimal levels of work while it’s closed.
