Various types of butterfly valve are versatile and efficient tools used in various industries for regulating flow. Their simplicity, ease of operation, and reliability make them a popular choice. Проте, it’s important to understand their classification, будівництво, and function to maximize their potential.

Butterfly valves are quarter-turn valves that use a disc-shaped element to regulate flow. The disc is perpendicular to the direction of flow when closed and parallel when open, and can be operated by a lever, handwheel, pneumatic actuator, or electric actuator.

These valves find application in chemical processing, food and beverage, фармацевтичний, очистка води, and HVAC industries, серед інших.

Farpro Valve manufacturers provide a wide range of general-purpose and specialty butterfly valves to numerous industries and businesses. We prioritize the best quality of butterfly valve products while keeping sales prices as low as possible.

General Types of Butterfly Valve Construction​

butterfly valve structure genenal

  • Корпус клапана: The body of a butterfly valve is a circular or oval tube containing the valve disc and seat. The valve body can be made of various materials, such as cast iron, ductile iron, carbon steel, нержавіюча сталь, and plastic.
  • Valve Disc: The valve disc of a butterfly valve is attached to the stem and rotates around the stem to control flow. The disc can be made of various materials such as cast iron, нержавіюча сталь, aluminum, and plastic. The shape of the disc can be round, oval, or even rectangular.
  • Стебло: The stem of a butterfly valve connects the disc to the actuator. It transmits the torque from the actuator to the disc, causing it to rotate. The stem can come in different lengths and materials, such as stainless steel, carbon steel, or aluminum.
  • Valve Seat: The seat of a butterfly valve is a ring-shaped element mounted inside the valve body. It provides a sealing surface for the valve flap to close. The seat can be made of various materials, such as rubber, PTFE, metal, or graphite.
  • Actuator: The actuator of a butterfly valve is responsible for controlling the rotation of the butterfly blade. The actuator can be manual, pneumatic, or electric. Manual actuators use a lever or handwheel to operate the valve. Pneumatic actuators use compressed air to rotate the disc, while electric actuators use an electric motor to drive the valve.

Classified by Actuation Method

butterfly valve electric

Electric Actuated Butterfly Valve

The electric actuated is a modern, versatile method of driving butterfly valves. It involves an electric motor that rotates the valve disc through a series of gears or a direct drive mechanism.
The electric drive allows precise control of the valve position and can be operated remotely using a control panel or computer.
It is typically used in applications that require frequent adjustments, such as water treatment and HVAC systems.

pneumatic butterfly valve

Pneumatic Butterfly Valves

Pneumatic actuation is a method of actuation for butterfly valves that involves the use of compressed air to rotate the valve disc.
It is typically used in industrial applications that require high torque and precise control, such as the chemical processing and oil and gas industries.

eccentric butterfly valve

Manual Butterfly Valves

Manual actuation is the most basic method of actuation for butterfly valves. It involves a lever or handwheel that is rotated manually to open or close the valve.
It is simple, reliable, and cost-effective, making it the best choice for small-scale applications that do not require frequent adjustments. Manual actuation is often used in residential and commercial buildings, where butterfly valves are used for water control.

Pulp And Paper Industry

Pulp And Paper Suppliers

The paper production process is divided into two parts: pulping and papermaking. The wastewater produced in the process, after treatment to meet the relevant national emission standards, are indispensable for the participation of various types of valves, включаючи засувки.

According to Farpro's years of valve experience, the main media encountered in the paper manufacturer are: slurry, пара, води, sewage and black liquor and other such media. Control valves for production media do not need to be specifically considered for high temperature, high pressure, strong corrosion, explosion-proof and other factors.

Butterfly valves are widely used in the pulp and paper industry to regulate the flow of fluids, such as pulp and chemicals. They are used in various applications, such as stock preparation systems, bleach plant systems, and coating systems. Butterfly valves are also used in the transportation of fluids, ensuring that the products are delivered safely and efficiently.

Chemical Processing

Chemical Processing

Some types of butterfly valves are commonly used in the chemical industry due to their ability to handle corrosive fluids. They are used to control the flow of chemicals through pipes and tanks, allowing for precise control over the process. Butterfly valves are also used in the transportation of chemicals, regulating the flow of fluids through tankers and pipelines.

Oil & Gas Marine Industrial

Oil & Gas / Marine Industry

Various types of butterfly valves are widely used in the oil and gas industry to regulate the flow of crude oil, natural gas, and other fluids. They are used in pipelines and tankers to control the flow of fluids, as well as in refineries to regulate the flow of fluids through various processing stages.

Farpro has concluded, based on global sales and data, that the demand for valves in the global oil and gas extraction industry and transportation industry continues to grow. This demand has led to the oil and gas industry's quest for deeper drilling pipelines and lower production costs, so technicians are taking greater care in selecting quality valve equipment and hardware.

Upstream, valves are used to control the flow of oil, from high-pressure injection systems to throttle blowout preventers.

Downstream, Farpro sees more challenges in the refining process of crude oil. The growing segmentation of the market provides many high-tech needs for the petrochemical industry, which is why there is a need for high-precision, high-quality valve production and design.
