Butterfly Valves

Butterfly valves are quarter turn having disc attached to a shaft with bearings facilitating rotation.
These are considered high-recovery valves since only the disc obstructs the valve flow path. The flow capacity is relatively high and the pressure drop across the valve is relatively low. These extended stem butterfly valves are used for limited throttling where a tight shut-off is not required.
As one of the most popular types of valves, butterfly valves are commonly used in various industries due to their ease of operation and cost-effectiveness. Also known as high performance butterfly valves, these work by using a disk to regulate the flow of fluids in a pipeline, which can be rotated to control the rate of flow. Butterfly valves manufacturers in India offer a variety of materials, sizes, and designs to suit different applications and requirements, making them a versatile and widely used valve type.
These high performance Butterfly valves are the most economical for more prominent lines i.e. chemical services, water treatment etc. available sizes are 2" to 48" & go up to 96". Butterfly valves generally have small face-to-face dimensions, so they weigh less than most other valves. Moreover, these comply with ASME face-to-face dimensions and pressure ratings enabling the valve to be easily retrofitted in line regardless of the manufacturer.
The UL approved butterfly valves with applicable standards for design include AWWA C204, API 609, MSS SP-69 and API 598 for testing requirements.


UL FM certification for valves ensures that they meet the safety and performance standards set by Underwriters Laboratories (UL) and Factory Mutual (FM) for use in fire protection systems. This certification is particularly important for valves used in commercial and industrial settings where fire safety is a critical concern.

UL-approved Butterfly valves are specifically designed and tested to meet UL FM certification requirements. These valves have undergone rigorous testing to ensure that they can withstand the high temperatures and pressures that may be encountered in fire protection systems. By choosing UL approved Butterfly valves, you can have confidence in the safety and reliability of your fire protection system.

FM and UL approval are two important certifications in the world of industrial valves. FM approval is issued by Factory Mutual Global, while UL approval is issued by Underwriters Laboratories. These certifications ensure that a valve meets certain safety and performance standards.

When it comes to UL approved Butterfly valves, they have undergone rigorous testing and evaluation to meet the safety standards set by Underwriters Laboratories. This certification indicates that the valve has been tested for safety, reliability, and performance and is suitable for use in a variety of industrial applications.

A butterfly valve is a type of valve that controls the flow of a fluid through a pipeline. It consists of a disk that rotates around a shaft to open or close the valve. Butterfly valves are commonly used in a variety of applications, including HVAC systems, water treatment plants, and industrial processes. They are often preferred over other types of valves because they are lightweight, require less space, and can be operated quickly. Additionally, these valves are cost-effective and can handle high flow rates with minimal pressure drop. Overall, these valves are a reliable and versatile option for controlling the flow of fluids in a wide range of applications.

Butterfly valves are used in a wide range of applications, from water treatment plants to oil refineries. They are named after their distinctive shape, which resembles that of a butterfly. When fully open, the disc of the valve is perpendicular to the flow, allowing for a low-pressure drop and minimal turbulence. When fully closed, the disc forms a seal against the valve seat, preventing flow.

If you are looking for a reliable butterfly valves manufacturer in India, it is important to choose a company with a proven track record of quality and customer satisfaction. Look for a manufacturer that offers a wide range of butterfly valves and related products, as well as excellent customer service and technical support.

A high-performance-type butterfly valve is a type of industrial valve that is commonly used to regulate the flow of fluids, gases, and slurries. This type of valve is designed to provide exceptional performance in high-pressure and high-temperature applications. High-performance butterfly valves are known for their reliable sealing capabilities and their ability to handle a wide range of media. They typically have a higher flow rate capacity than standard butterfly valves and are often used in critical applications that require precise control. With their simple design, low maintenance requirements, and excellent durability, high performance butterfly valves are a popular choice for a wide range of industries, including oil and gas, chemical, and power generation.

The three types are:

  • The concentric butterfly valve is the most commonly used type, and it has a disk that is centered in the pipe bore.
  • The double-offset butterfly valve has an offset stem, which reduces seat wear, and it is suitable for high-temperature applications.
  • The triple offset butterfly valve has a metal seat, and its sealing mechanism is based on a laminated seal ring, which makes it suitable for applications that require high reliability and low leakage.

In addition to these three types, there are also extended stem butterfly valves, which are a variation of the triple offset butterfly valve. It has a longer stem, which allows for installation in pipelines with insulation.

A stem butterfly valve is a type of valve used to regulate the flow of liquids or gases in pipelines. It is a quarter-turn valve that uses a disc as a closure element, rotating on a stem. When the valve is fully open, the disc allows full flow through the pipe, while in a closed position, it creates a seal and stops the flow

Extended stem butterfly valves are designed with an elongated stem that extends beyond the insulation of pipelines, making them suitable for use in applications where the temperature of the fluid being transported is high. These valves are commonly used in industries such as chemical, petrochemical, and oil and gas.
