What are the Characteristics of Butterfly Valve Flow Control?

Butterfly valves are valves in fluid dynamics that are used to control the flow of liquids, gases and slurries. Fujian Xinghuo Valve Co., Ltd., as a butterfly valve supplier, will reveal the vannes papillon control characteristics and butterfly control valve flow characteristic in depth.

Butterfly Valve Introduction

Butterfly valves are a flow regulation tool named because of their appearance similar to the wings of a butterfly. The butterfly plate further moves and rotates the valve body 90 degrees to open or close the flow. Its simple design, light weight and compactness make it a cost-effective alternative to other valve types.

Main components of butterfly valves

1. The cylindrical part located between the pipe flanges and farthest from the fluid. It is located on the left side of the pipe.

2. The circular part located in the middle of the pipe that controls the flow of the fluid, that is, the rotating part.

3. The part that connects the actuator or handle to the valve disc is called the valve stem.

4. The valve seat is located on the right side of the pipe and seals the connection between the valve disc and the valve body when in the closed position, that is, preventing leakage by closing the valve.

When the disc is in line with the direction of fluid flow, the valve opens and fluid flow is impeded. However, if the disc is at right angles to the direction of the fluid, a tight seal is formed and the fluid will not be able to pass through. In this arrangement, the flow resistance of the fluid will be as small as possible.

Butterfly Valve Control Characteristics

1. Compact Design

The compact design of the butterfly valve is its widely recognized feature. The valve is small in size and light in weight, easy to install in a small space, and suitable for a variety of industrial applications. This design feature not only reduces the weight of the piping system, but also reduces the material cost and subsequent installation cost of the system.

2. Fast Operation

A major feature of the butterfly valve is its quarter-turn mechanism, which allows for fast opening and closing. This is essential for emergency shutdown applications where speed is critical. Easily switching the flow rate not only ensures safety but also improves efficiency.

3. Versatility

The versatility of the butterfly valve is also reflected in its ability to handle a variety of media, such as water, air, steam, chemicals and slurry. This makes the valve an ideal multi-functional valve in process flows such as water treatment, chemical production and HVAC systems.

4. Cost-effectiveness

Butterfly valves are superior to other valves in terms of cost because they are cheaper. The product design is simple and the production process is practical.

Butterfly Control Valve Flow Characteristics

1. Flow control

This type of valve is best suited for flow regulation and control.

2. Pressure handling

Butterfly valves are able to withstand moderate pressures, and even the so-called “high-performance” butterfly valves can work normally at moderate temperatures. Therefore, they can operate in more severe conditions without the danger of low pressure.

3. Durability

In addition to their compact design, which makes the valve take up less space, butterfly valves are also widely recognized for their durable construction. In addition, butterfly valves are usually made of corrosion-resistant materials, which solves the problem of wear and avoids the need for frequent replacement of parts.

4. Energy saving

The energy saving of butterfly valves lies in their streamlined design, which makes their operation as energy-efficient as possible by reducing pressure drop. These valves can reduce energy losses and reduce operating costs.

Application of butterfly valves

In the field of water treatment, butterfly valves can excellently control the flow of water treatment plants, thereby improving the operating efficiency of the plant. In the field of chemical processing, these valves can safely and effectively control the flow of chemicals. In HVAC systems, butterfly valves are used to regulate the flow of air through the coils.

Conclusion

Butterfly valves are suitable for regulating the flow of liquids and gases in a variety of applications. The control characteristics of butterfly valves – including compact design, fast operation, versatility and cost-effectiveness – make them an indispensable component in many industries. In addition, the flow characteristics of butterfly valve control valves, such as excellent flow control, pressure handling, durability and energy saving, further enhance their appeal.
