PTFE ball valve seat, also known as PTFE valve seat, is the most commonly used seat seal for ball valves, according to the molding method of molding and lathe processing of two ways, lathe processing of the seat accuracy of 0.02mm, molded seat tolerance 0.1mm; according to the temperature of the product can be divided into carbon fiber seat, graphite seat, PPL seat, polyphenylene ester valve seat and so on. Our products are processed with new tetrafluoroethylene fine particles. Characteristics: It has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stickiness, electric insulation and good anti-aging resistance. Pure PTFE valve seat can work for a long time under the temperature from +200℃ to -180℃, and the filled modified PTFE material has more obvious improvement than the pure PTFE products in terms of abrasion resistance, thermal conductivity, anti-glutinization and self-lubrication. It can be used for sealing in the temperature range from -180℃ to +300℃. The company has many years of experience in the production and processing of ball valve seats and butterfly valve seats, and specializes in the research and development of high-temperature and low-temperature valve seats and seals.
It has excellent characteristics such as high temperature resistance, corrosion resistance, abrasion resistance, good sealing, etc. It is widely used in the manufacture of valves for chemical, petroleum, pharmaceutical, food and other industries.
High temperature resistance
The PTFE valve seat has very high high temperature resistance and can be operated at extreme temperatures from -200℃ to +250℃ without deformation or embrittlement due to temperature change, ensuring the normal operation of the valve. Under high temperature, the PTFE seat can still maintain good elasticity and wear resistance, and will not produce leakage due to temperature changes.
Corrosion resistance
PTFE valve seat has strong corrosion resistance and can resist the erosion of many chemical substances, such as acid, alkali, salt, etc. Under the action of corrosive media, the PTFE valve seat can resist the erosion of many chemical substances. Under the action of corrosive media, PTFE valve seat will not produce dissolution, cracking, deformation and other phenomena to ensure the normal operation of the valve.
Abrasion resistance
PTFE valve seat has good abrasion resistance, can not be damaged under the high-speed fluid, and will not leak due to abrasion. Under the high load working conditions, the PTFE seat can still maintain good elasticity and durability to ensure the stable operation of the valve for a long time.
Good sealing
The PTFE seat has good sealing performance, which can effectively prevent the leakage of media. Under the action of high pressure, high temperature and high speed fluid, the PTFE seat can still maintain good sealing performance to ensure the normal operation of the valve.
In summary, PTFE valve seat is a high-performance valve seat material, with high temperature resistance, corrosion resistance, abrasion resistance, good sealing and other excellent characteristics, widely used in chemical, petroleum, pharmaceutical, food and other industries in the manufacture of valves. If you need valve manufacturing materials, you may want to consider PTFE valve seat, which will surely bring help for your product quality and performance improvement.
