PTFE lined butterfly valve use occasions and operating temperature?

PTFE lined butterfly valve is a common industrial valve, widely used for fluid control in chemical, petroleum, pharmaceutical, food and other fields. It is characterized by simple structure, light weight, easy operation, good sealing performance, etc., so it is widely used in various occasions.

First of all, PTFE lined butterfly valves are suitable for the control of corrosive media. In the chemical industry, many media have strong acid and alkali properties, which impose strict requirements on valve materials. The main material of the PTFE lined butterfly valve is carbon steel or stainless steel, while the valve seat, valve plate and other parts are lined with fluorine plastic, which has strong corrosion resistance and can effectively prevent the medium from corroding the valve and ensure the purity of the medium. and circulation security.

Secondly, PTFE lined butterfly valve is suitable for the control of high temperature media. In industries such as petroleum and refining, it is often necessary to control the flow of high-temperature media. PTFE lined butterfly valves can withstand work in high-temperature environments. The fluorine-plastic lining has good high-temperature resistance and can maintain the normal operation of the valve under high-temperature conditions without softening or deformation.

In addition, PTFE lined butterfly valves are also suitable for food and pharmaceutical industries. These industries have very high hygienic requirements for the medium, and require valves with good sealing performance and corrosion resistance to ensure the purity and safety of the medium. PTFE lined butterfly valves exactly meet these requirements. Its fluoroplastic lining has excellent sealing performance and hygienic performance, which can effectively prevent leakage and contamination of the medium and ensure product quality and safety.

Regarding the service temperature of PTFE lined butterfly valve, generally speaking, it can work normally in the range of -40°C to 200°C. When the medium temperature exceeds 200°C, valves of other materials or models need to be selected according to specific usage conditions to ensure the normal operation and life of the valve.

In general, PTFE lined butterfly valves play an important role in the control of corrosive media and high-temperature media, and can meet the strict requirements for valves in chemical, petroleum, pharmaceutical, food and other industries. Its advantages include simple structure, light weight, easy operation, good sealing performance, and good corrosion resistance and high temperature resistance. However, when using PTFE lined butterfly valves, it is necessary to select appropriate materials and models according to the nature of the medium and process requirements to ensure the normal operation and reliability of the valve.
