Butterfly valves
The strengths of butterfly valves: fast actuation and handling of large quantities of fluids.
Butterfly valves are an excellent solution when it comes to allowing or interrupting the flow of a fluid. The name derives from the shape of the shutter and its movement. It is, in fact, a disc crossed by a stem. The disc rotates 90 ° around an axis perpendicular to that of the pipeline and when the disc presses on the seal seat, the flow stops.
The butterfly valve is used for handling large flows of liquids but also in the case of gas. It is a fast-acting device, but it can also be activated with an electric or pneumatic actuator to facilitate commissioning, especially in the case of large valves or valves which are difficult to reach.
With butterfly valves, limited space is not a problem.
Among the main advantages of the butterfly valves there is also the small footprint that allows you to optimize space. This is a great added value in industrial plants where the problem of space is very important.
Furthermore, the valve body can be made in different ways so as to allow different joining methods. We have, for example:
- DOUBLE FLANGE butterfly valves, where the two perforated flanges are connected to the pipes by means of bolts
- WAFER type butterfly valves, characterized by four centering through holes that allow connection with only four bolts
- LUG type butterfly valves, where the connection is guaranteed by different threaded fixing holes that require a set of screws for each side
