A Brief Discussion on PTFE lined valve

What is PTFE lined valve? Fluoroplastic lined corrosion-resistant valve is actually another alias for PTFE lined valve. and check valve The different working principle is that PTFE lined valves use PTFE resin (or profiles processed) to be embedded (or molded) on the inner wall of steel or iron valve pressure parts (the same method applies to the inner lining of various pressure vessels and pipeline accessories) or the outer surface of valve internals, and use its performance in resisting strong corrosive media to make various valves and pressure vessels.
Fluorine lined valves use lining technology for all areas that the medium inside the valve body can reach. The lining material is generally made of fluoroplastics such as FEP (F46) and PCTFE (F3), which can be used for various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, and various organic acids, as well as strong acids in rotor pumps Fluorine lined DC globe valve Strong oxidizing agents and other corrosive media pipelines, but fluorine lined valves and fluorine lined DC globe valves are greatly limited by temperature (only applicable to media between -50 ℃ and 150 ℃). Valves that can be made with fluorine lined plastics include: Fluorine-lined Butterfly Valve The Fluorine-lined ball valve Fluorine lined globe valve, fluorine lined diaphragm valve Fluorine lined gate valve Fluorine lined plug valve, Clamp type fluorine lined butterfly valve Wait.
Application and use of fluorine lined valves:
With the rapid development of modern industry, clamp type fluorine lined butterfly valves and their various pipeline accessories have been rapidly applied and promoted in various fields such as petroleum, printing and dyeing, and chemical engineering, demonstrating strong vitality. As a project in engineering, it has attracted great attention and favor from various engineering design and construction units, and is a sunrise product with market potential.
Fluorine lined valves have dual functions of switching and flow regulation, which can easily open and close the gas path without affecting the flow. Fluorine lined check valves ensure the repeatability of flow. Slowly opening reduces the impact of instantaneous pipeline pressure on the instrument. A damper has been added to greatly extend the service life of the needle valve. Fluorine lined valves are specifically designed to control corrosive or highly corrosive media. The surface of the valve body cavity is covered with various fluoroplastics for selection, suitable for different working temperatures and fluid pipelines. They have the characteristics of high strength and good corrosion resistance.
