A butterfly valve is a machine tool that regulates, restricts, or stops the pressure and flow of gases, liquids, or slurries through a piping system. The valve system operations occur through the opening, closing, or partly blocking different pathways.
This mechanical equipment is used in several industries, including oil and gas, water treatment, and more. Let’s find out more about the significance of industrial butterfly valves in many industrial applications and why they are widely used compared to other valve types.
An industrial butterfly valve is used to regulate both liquid and gas flow through pipes. It is a type of quarter-turn motion valve that can open and close whenever the rotating disc is turned at ninety degrees. Moreover, a butterfly valve is used in several industries due to its compatibility, reliability, and low maintenance features.
In fact, there is a substantial reliance rate on the industrial butterfly valve industry because of its extensive utilization in different applications. This includes the automation, wastewater treatment, petrochemical, chemical, food and beverage, and pharmaceutical segments.
Basically, butterfly valves consist of four main parts: body, disc, stem, and seat. Each segment has a vital function.
Butterfly valves have bodies that can fit between two pipe flanges and the most common body structures are wafer and lug. The lug’s body has protruding lugs that present bolt holes matching those in the pipe flange. On the other hand, a wafer’s body does not contain protruding lugs. Instead, the wafer is sandwiched between pipe flanges, then the flange bolts surround its body.
The stem part could be a one-piece or two-piece shaft structure. It is protected from the media in most resilient seated designs, allowing an efficient material selection concerning cost and mechanical properties. On the contrary, the stem is in contact with the media in high-performance butterfly valve designs.
The disc is a moveable part that allows and restricts flow through the valve, rotating in one quarter-turn or ninety degrees. Thus, it is the flow closure in a butterfly valve, the counterpart of a plug when it comes to a plug valve, a ball in an industrial ball valve, or a gate in a gate valve.
The seat is a surface inside the body that comes into contact with the disc to provide a tight shutoff. It can be a fireproof seat, resilient seat, or metal seat used to prevent compressed fluids or combustion gasses from getting into the manifold.
Butterfly valves are lightweight and only require smaller space compared to other industrial valves in the business. Due to its compatibility, it is manageable and only needs a ninety-degree rotation of the handle to support a full opening or closing of the valve. Also, manufactured by a reliable industrial valve supplier, it is high-performing, it is easy to maintain and very cost-efficient.
Butterfly valves’ disc part tends to face the flow even if it is fully opened, leading to a pressure switch over the valve. Also, choked flow and possible cavitation are a worry when industrial butterfly valves perform. Moreover, there are instances that they have a poor sealing function, and throttling is restricted to low-pressure drop applications.
Dombor, as a butterfly valve manufacturer, supplies custom valves for your business need. There are main types of butterfly valves. First is the rubber-lined valve, which is less expensive compared to other types. Then there are plastic-lined valves are used for sanitary and abrasive applications. On the other hand, the metal types are utilized for high-pressure and high-temperature applications.
Here are the different butterfly valves segmented by body types.
A wafer style butterfly valve features two or more centering holes to support installation between pipes. They are widely used since they are lighter and cheaper.
A lug style features threaded metal bolts around the entire body. Its main application is to connect and disconnect piping systems – from one side without distributing on the other side of the system. A lug style can replace a wafer valve. However, you can’t switch from a lug to a wafer.
Flange butterfly valves are known for their large sizes. They are used for various methods of piping connection. These types have raised or winged edges in the enclosure so that they can be fastened in between two pipes.
The welded butterfly valve is used for very high-pressure operations. Since most plastic-lined valves are very limited to PN10/16 (150#) flanges, the welded butterfly valve is rarely seen with plastic-lined valves. So, this type is typically made from stainless steel, aluminum, or bronze elements.
Butterfly valves are also categorized by their disc alignments. Here’s zero, double, and triple offset.
Zero offset butterfly valves are what we know as rubber seated or resilient seated butterfly valves. These valves feature a central structure of its stem, disc, and body aligned in the same position. Thus, it is easy to manufacture because of its simple design.
Double offset butterfly valves, also known as high-performance butterfly valves, are used in many applications nowadays. Consider these types as an improved and better version of valves compared to the design and features of single offset butterfly valves.
Triple offset butterfly valves are designed based on the design of a double offset butterfly valve. Apparently, there are three offsets in triple offset butterfly valves. Two are situated in identical positions similar to a double offset butterfly valve. Then there is the third offset, which is geometrically aligned on the seating surface.
