The Wafer-Type Fluoropolymer-Lined Soft-Seal Butterfly Valve For Highly Corrosive Media

Butterfly Valve Introduction

This is a wafer-type PTFE-lined soft-seal butterfly valve, belonging to the category of industrial valve equipment.

This butterfly valve uses a blue cast iron or cast steel valve body, with an internal fluoroplastic (such as PTFE) sealing structure, providing excellent corrosion resistance. It is suitable for pipeline systems handling highly corrosive media (such as acid and alkali solutions, organic solvents) in industries such as chemical and pharmaceutical manufacturing, used to control the flow of fluids. The valve is equipped with a manual lever-type actuation device, allowing for convenient and rapid opening and closing of the butterfly plate.

Applications of Butterfly Valves

Due to their excellent corrosion resistance and sealing performance, wafer-type fluoropolymer-lined soft-seal butterfly valves are mainly used in the following scenarios:

Chemical Industry: In pipelines transporting acid and alkaline solutions (such as sulfuric acid, hydrochloric acid, and sodium hydroxide solutions) and organic solvents (such as methanol, ethanol), they are used to control the flow of media and effectively resist the erosion of highly corrosive media.

Pharmaceutical Industry: In pipelines for the production and transportation of pharmaceutical raw materials (such as various chemical reagents and pharmaceutical solutions), they ensure the purity of the media and the corrosion resistance of equipment, meeting the stringent hygiene and corrosion resistance requirements of the pharmaceutical industry.

Food Industry: In pipelines processing and transporting certain special food raw materials (such as acidic beverages and flavorings), they provide both corrosion resistance and ensure food hygiene and safety.

Environmental Protection Industry: In pipelines handling corrosive wastewater (such as wastewater containing acidic or alkaline components) in wastewater treatment plants and corrosive media (such as acidic waste gas condensate) in waste gas treatment, they enable the control of media.
