Butterfly Valves

Butterfly valves are fittings for regulating and shutting off liquids and gases in pipeline systems. The valves consist of a round body with a rotating disc that opens or closes the flow by 90-degree rotation. They are used in industrial applications such as water supply, chemical industry, and energy technology.

Butterfly valves are not ball valves, gate valves, or check valves, but exclusively fittings with a rotating disc construction.

Butterfly Valves: Frequently Asked Questions

How do butterfly valves work?

Butterfly valves work by rotating a valve disc 90 degrees within a round housing. In the open position, the disc is parallel to the flow, while in the closed position it sits perpendicular. This simple operating principle enables quick and reliable control of liquids and gases in pipeline systems.

Which industries are butterfly valves suitable for?

Butterfly valves are suitable for diverse industrial applications, particularly in water supply, chemical industry, and energy technology. They are also used in the gas, petrochemical, and food industries. These valves are especially suited for applications requiring fast opening and closing as well as compact design.

What advantages do butterfly valves offer over other valve types?

Butterfly valves are characterized by their compact design, low weight, and quick actuation. They require less installation length than gate valves or ball valves and are generally more cost-effective. Due to their simple construction, butterfly valves also enable straightforward maintenance and reliable operation over extended periods.

Can butterfly valves be used for flow control?

Yes, butterfly valves can be used not only for complete shut-off but also for regulating flow rates. By partially opening the valve disc, flow can be continuously regulated. For precise control tasks, butterfly valves are frequently combined with electric or pneumatic actuators that enable exact positioning.

Where can I source butterfly valves in Germany?

Butterfly valves can be sourced through specialized distributors such as SL Armaturen & Antriebe from Korschenbroich. The company distributes industrial valves from European and North American manufacturers for Germany and parts of Europe. Such specialized dealers offer not only butterfly valves but also compatible actuators and technical consultation for industrial applications.
