There is a kind of valve used to control the flow of the fluid in pipelines and systems. This type of valve is called a butterfly valve. It uses a quarter-turn mechanism to control the flow. Due to many beneficial features, these valves are used in various applications, such as oil production and food processing. There are several types of valves: double-flanged butterfly valve, dual cast iron butterfly valve, lung type butterfly valve, T-burst valve, and wafer butterfly valve. Each of these types has its own technical specifications to offer a unique application in different industries. At YasminTrading, we provide you with the best of these types to help you have the safe, reliable, and durable application you are looking for.

What is a Butterfly Valve?

According to Hawle, a butterfly valve is a kind of flow control valve that regulates the flow. Like other control valves, it uses a butterfly on the central shaft.

Applications of Butterfly Valves

Butterfly valves are applied in different conditions to regulate fluid flow in pipelines. However, in some industries and projects, they come in handy the most. Here are a few butterfly valve applications.  
  • These valves are mainly used to regulate the fluid flow, on-off control over fluids, and isolation.
  • Butterfly valves are typically used in industries such as oil, gas, and power production.
  • The food and beverage industry and chemical processes commonly apply this type of valve as well.

Benefits of Butterfly Valves

It is a matter of course that these control valves have many benefits in different applications. This is why these high-performance butterfly valves are widely used for various conditions and projects.  
  • Their compact size is a significant feature that is hard to ignore. This leads to their being lightweight, which makes these valves perfect for use in limited spaces.
  • With the same flow capacity, butterfly valves are the cheapest type of valve that can be found.
  • These valves provide a very fast operation with a quick opening and closing.
  • The pressure drop is at the most minimized level. This enables a more efficient flow.
  • Butterfly valves are perfect for emergency shutdowns.

What Are the Types of Butterfly Valves Available at YasminTrading?

Butterfly valves consist of several different types. Each of these flow control valves has its specifications. YasminTrading provides you with the most practical and useful types of butterfly valves.

Double Flanged Butterfly Valve

A double-flanged butterfly valve is a common type. As the name reveals, there are two flanges on both ends of the valve. These two flanges ensure a safe and leak-proof connection. These valves offer reliable control over fluid flow, creating a secure connection.  
  • They are installed easily, and the removal for any repair would not disrupt the pipeline.
  • This type has a quarter-turn mechanism, which enables a quick opening and closing.
  • Double-flanged butterfly valves can be used in various industries for several purposes, such as flow regulation and isolation.

Ductile Cast Iron Butterfly Valve

Another type of butterfly valve is a ductile cast iron butterfly valve, the body of which is made of ductile cast iron. This type of valve also provides efficient control in different applications. These valves are used when durability, reliability, and strength are essential.  
  • This type has a quarter-turn mechanism to ensure flow regulation. However, its operation is the same as that of normal butterfly valves.
  • The body of this valve is made of ductile cast iron. A ductile cast iron butterfly valve owes its strength to the material it is made of.
  • These valves are even resistant to corrosion and corrosive fluids.
  • They are mainly used in water service pipelines and HVAC systems.

Lug Type Butterfly Valve

Referring to Belimo, the lug-type butterfly valve has a more complex mechanism. Its design has threaded inserts on both ends. These valves offer easy installation, maintenance, and removal and a customizable design to meet specific needs.  
  • The lugs offer simple installation between two flanges. There is no need for nuts or bolts.
  • The downtime is significantly reduced with these valves. In addition to that, the removal process is much easier.
  • Lug-type butterfly valves are mainly used in industries that require regular maintenance or replacements.
  • The operation of these valves is almost the same as other types, including a quarter-turn mechanism.

T-Butterfly Valve

T-butterfly valves, also known as triple-offset butterfly valves in the industry, are of superior design and specifications. As a result, they are useful in situations in which standard butterfly valves would not perform well enough. These valves have unique performance characteristics.  
  • These valves offer marvelous benefits such as longer service life, reduced wear and tear, and perfect shut-off capability.
  • They work with three individual offsets, which are offsets of the disc and seat that create a bubble-tight seal.
  • T-butterfly valves are commonly applied in conditions with high pressure and high temperature.
  • They are also a suitable choice for applications with the presence of corrosive media.

Wafer Butterfly Valve

Wafer butterfly valves are a sort of butterfly valve specifically designed to fit within two flanges. This makes them an excellent choice for saving space in various applications and for controlling flow in smaller spaces.  
  • These valves are utilized in oil and gas production. Chemical and food processing are useful for flow control.
  • Bolts are used to clamp these valves between flanges in pipelines. This makes them a good choice for easy installation and removal.
  • These valves have a wafer-thin body, which is why they are called that. This helps them fit between the flanges.
  • They have a compact design, which makes them perfectly suitable for usage in more limited spaces.

Other Butterfly Valves

Though the above are the most common types of butterfly valves, there are still more types. Resilient-seated butterfly valves, PTFE-lined butterfly valves, electric or pneumatic actuated butterfly valves, and high-performance butterfly valves are some of the other types of butterfly valves. The common feature between all these types is controlling the fluid flow reliably.   This table shows the technical specifications of different types of butterfly valves perfectly.
