What are the advantages of a wafer butterfly valve?

Wafer butterfly valves are a kind of butterfly valves having a simple structure. The disc of wafer butterfly valves is a plate, swinging with a valve shaft to turn on or off valves. Wafer butterfly valves are used for cutting off and throttling in pipelines. Industrial specialized wafer butterfly valves have a wide applicable pressure range. Wafer butterfly valves have a large nominal diameter, whose body is made of carbon steel. Sealing ring in the disc of the wafer butterfly valve is made of a metal ring, instead of a plastic ring.

How can a wafer butterfly valve be used?

What are the advantages of wafer butterfly valves?

What are the disadvantages of wafer butterfly valves?

How can a wafer butterfly valve be used?

Wafer butterfly valves can be used in the gas pipeline of the sulfuric acid industry. The inlet and outlet of the blower in front of the furnace, the relay fan, the main blower and the preheater can be found out wafer butterfly valves. Wafer butterfly valves are also be used in the electric demisting series and the connection valve with the use of cut-off gas.

Wafer butterfly valves are used in the sulfur burning, conversion and dry absorption section of the sulfur-burning sulphuric acid plant. It is the preferred device of butterfly valves for the sulphur-burning sulphuric acid plant. A wafer butterfly valve is regarded by the majority of users as good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, The flexible, safe and reliable wafer butterfly valve has been widely promoted and used.

Wafer butterfly valve is also widely used in SO2, steam, air, gas, ammonia, CO2 gas, oil, water, salt water, lye, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid in the chemical, petrochemical, smelting, pharmaceutical, food and other industries. One of the functions of wafer butterfly valves is to regulate and intercept on pipelines of other media. Wafer butterfly valves can also be seen as low pressure pipelines to regulate media.

What are the advantages of wafer butterfly valves?

The wafer butterfly valve turns on or turns off conveniently and rapidly with less force. The wafer butterfly valve has less fluid resistance so that it can be operated frequently.

The wafer butterfly valve has a simple structure, small size. The wafer butterfly valve has a short face to face dimension, less volume and light weight, which is suitable for large diameter valves.

A wafer butterfly valve can be used for transmitting mud that fewer liquids are stored at apertures of pipe.

Sealing face of wafer butterfly valve is generally med of rubber or plastic. Under low pressure, wafer butterfly valves can realize good sealing.

Wafer butterfly valves have excellent regulation performance.

When wafer butterfly valves turn on completely, the passageway of seat has a large effective flow area and less fluid resistance.

The wafer butterfly valve has less torque. The pressure on the disc at the two sides of the spindle is almost equal, causing contrary torque. Thereby, the wafer butterfly valves can be opened with less force.

What are the disadvantages of wafer butterfly valves?

However, there are few disadvantages of the wafer butterfly valve as listed below.

Throttling service of wafer butterfly valve is limited to low differential pressure.

Disc movement of the wafer butterfly valve is affected by flow turbulence.

The wafer butterfly valve disc is always under pressure and can interrupt the flow even in an open position.

Possibility of cavitation and choked flow is a concern

The wafer butterfly valve has a poor sealing function under high pressure and high temperature.

A wafer butterfly valve is not suitable for high differential pressure.

Learn more about wafer butterfly valve can know the advantages of the wafer butterfly valve and the disadvantages of the wafer butterfly valve. In the process of butterfly valve development, a number of very powerful companies have emerged, such as Tianjin Worlds Valve Co., Ltd. Our company knows how to innovate while developing, and will also go out in the process of introducing wafer butterfly valve.
