Have you ever thought about how fluid is handled in industrial operations for operations that need precision? A high-quality valve is used in order to stop or enhance the flow of the fluid. Butterfly valve is also one of these. It consists of a disc-shaped element that rotates on a shaft, similar to the butterfly wings. It is used to control the flow of fluid or liquid, offering minimal resistance. In this post, we will understand the crane butterfly valve.
What is a Butterfly Valve?
The butterfly valve is used for regulating the flow of fluids, slurries, and pipelines. They are known for their quick operation, simple design, and relatively low cost. It makes them suitable for a wide range of applications.
How Does the Butterfly Valve Work?
The butterfly valves are quarter-turn valves that are best used for the stop/start of media flow in pipelines. When the valve handle is turned 90°, it either opens or closes completely. Throttling can be a bit tough, but these valves can still be used for regulating purposes.
A butterfly valve can be operated manually, pneumatically, or electrically through an actuator. Using the actuator can help in controlling the valve. The actuator will be connected to the disc, and it will move the disc according to the required operation.

For each type of operation, there is a particular kind of tool that helps in the actuation. For example, pneumatically controlled butterfly valves have a piston attached to them. Technically speaking, this is the best method to control a butterfly valve as it enables quick shut-off and turn-on capacity.
Parts Of a Butterfly Valve
Body
The body of a butterfly valve fits between two pipe flanges, having two standard designs, lug-style and wafer-style. Both designs permit easy installation and maintenance.
Disc
A disc is installed inside the valve body to control the fluid flow, operating similarly to a gate or ball valve. It is the same diameter as the pipe it attaches to and can even pivot horizontally or vertically, depending on the stem orientation.
Stem
Although the stem is the smallest part of a butterfly valve, it still plays a significant role. It is used to connect the disc inside a valve to the handle outside a valve, thus allowing the device to open or close. In the most resilient seated designs constructed by butterfly valve manufacturers, the stem is isolated from the media to permit an efficient selection of material regarding the cost and mechanical properties.
Seat
A seat is one of the most critical components of a butterfly valve, as any damage to it may cause leaking. Sometimes, it is also referred to as the valve liner. It is typically made using elastomeric materials having similar properties to rubber. Polymer seats of a flanged butterfly valve avoid leakages between the seat and disc by pressing, locking, or bonding to the body.
The seats run along the length of the inner diameter of a butterfly valve. In high-performance valves, shutoff is offered by an interference-fit or a line-energized seat design. The pipeline pressure increases the interference between the seat and disc edge. Metal seats are also provided in high-performance valves to allow their usage even at higher temperatures.
