Introduction to PTFE lined valves

PTFE lined valve Introduction

PTFE lined valve, also known as fluoroplastic lined corrosion-resistant valve, is a type of valve and pressure vessel made by molding (or embedding) polytetrafluoroethylene resin (or profiles processed) onto 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, utilizing its performance in resisting strong corrosive media.
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 are 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 valves, etc.

Application and use of fluorine lined valves:
With the rapid development of modern industry, Clamp type fluorine lined butterfly valve The rapid application and promotion of various pipeline accessories in various fields such as petroleum, printing and dyeing, and chemical industry have shown 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 rate, check valve Ensuring the repeatability of traffic. 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.
