Ptfe Is The Key To The Excellent Performance Of Ptfe Lined Valves

Lined Valve is also known as fluoroplastic lined corrosion-resistant valve. It is to press polytetrafluoroethylene on the inner surface of the valve by molding to improve the corrosion resistance of the valve. Therefore, the key to the performance of PTFE lined valves is polytetrafluoroethylene.
Polytetrafluoroethylene is commonly known as the king of plastics. It was developed by the United States. It has not been widely used in the pump and valve industry for a long time, but its performance has quickly become popular. Polytetrafluoroethylene can not only resist molten alkali metals, elemental fluorine, etc., but also presents random changes in the alternation of concentrated and dilute corrosive media such as sulfuric acid and hydrochloric acid of various concentrations. Therefore, embedding it in the inner wall of the valve not only overcomes the defect of low strength of polytetrafluoroethylene, but also solves the disadvantage of poor corrosion resistance of valve materials. Polytetrafluoroethylene also has chemical stability, good anti-fouling and anti-sticking properties, low friction coefficient, good anti-friction lubrication, and using it as a sealing pair for valve opening and closing can well reduce friction, reduce operating torque, and increase the service life of PTFE lined valves.
