Product Overview

Butt-welding hard seal butterfly valve is a high-performance valve designed for high-pressure pipelines, widely used in petroleum, chemical, electric power, natural gas and other industrial pipeline systems. The valve is suitable for water, steam, gas, oil and some corrosive media, especially for high temperature, high pressure and poor working conditions of fluid control. Butt-welding hard seal butterfly valve adopts hard metal sealing material with superior sealing performance, which can operate stably for a long time under high temperature and high pressure environment, avoiding the abrasion and aging problems of traditional soft seal valves. Product features include strong sealing, high temperature and corrosion resistance, abrasion resistance, compact structure, easy operation, and suitable for large flow of fluid control. By butt-welding connection, the valve is more closely connected to the pipeline, ensuring system stability and reducing the risk of leakage. The main function is to efficiently cut off, regulate and control the fluid in the pipeline, which is widely used in occasions requiring high sealing, high pressure and high flow rate. Butt-welding hard seal butterfly valve has become an indispensable and important equipment in industrial pipeline system by virtue of its excellent performance.
