Butterfly valve/ Butterfly vlave
A butterfly valve is a type of valve with a butterfly-shaped valve body controlled by a lever, crank or electrical signal used to open and close fluid systems to help fluids pass through the valve or stop them. Butterfly valves can adjust the fluid flow depending on the opening angle of the valve. Valves come in a variety of designs and sizes suitable for installation in many systems.
Butterfly valves are composed of a controller and a butterfly valve body
Controller: helps the operator control the opening and closing of the valve. The controller includes types such as levers, cranks, and electrical signals that are designed appropriately to help the operator easily open and close the valve.
The butterfly valve body is the place that directly interacts with the fluid flow. In the valve body there is a butterfly wing used to prevent or allow fluid flows to pass through. The valve shaft connects the butterfly wing to the controller to help the opening and closing process. becomes easier. And some other parts included in the valve.
Each type of butterfly valve will be applied in different environments to best suit the installation system used, specifically:
- Stainless steel butterfly valves are widely used in environments with high temperatures, high pressures, environments with corrosive substances such as acids, bases, salts,...
- Cast iron butterfly valves are used in common water treatment systems
- Microbiological butterfly valves, plastic butterfly valves used in clean water systems, pharmaceuticals, food,...
- Flanged butterfly valves are used in large systems such as machinery in factories,...
