BUTTERFLY VALVES
What are butterfly valves?
Butterfly valves are flow control devices that use a rotating disc to open, close, or regulate the flow of fluids in a pipe. They operate by turning a 90° angle, allowing for quick and efficient operation.
What are butterfly valves used for?
They are used to regulate or interrupt the flow of liquids, gases, or slurries in industrial systems. They are especially common in water networks, industrial facilities, HVAC systems, and chemical processes.
How does a butterfly valve work?
It is characterized by its simple operation. It consists of a circular disc that rotates on its own axis. When the disc is parallel to the flow, the valve remains open; when it is positioned perpendicular to it, it completely blocks the flow of fluid.
What types of butterfly valves are there?
The most common models are:
- Manual butterfly valves.
- Lever-operated butterfly valves.
- Butterfly valves with reducer.
- Pneumatic butterfly valves.
- Electric butterfly valves.
- Wafer butterfly valves.
- Lug butterfly valves.
What advantages do they have over other types of valves?
Butterfly valves are notable for their compact design, light weight, and fast response. Furthermore, they require less maintenance and are more economical in larger diameters compared to ball or gate valves.
What types of drives can they have?
Butterfly valves can be operated in different ways: manually (lever or handwheel), pneumatically, electrically, hydraulically.
Are butterfly valves suitable for high pressure?
It depends on the type. Standard (concentric) butterfly valves are used at low or medium pressures, while double or triple eccentric versions are designed for more demanding applications.
Do butterfly valves require maintenance?
They require relatively low maintenance due to their simple design, although it is advisable to periodically check the condition of the disc, seat and sealing elements to ensure their watertightness.
