Made of stainless steel materials such as 304, 316, etc., it has good corrosion resistance, high temperature resistance, and mechanical strength, and can adapt to various harsh working environments. The valve seat is made of PTFE material, which has extremely excellent chemical stability and can resist corrosion from various strong acids, strong alkalis, and organic solvents. At the same time, it has an extremely low friction coefficient and good self-lubricating properties.
Standard export wooden case packaging ensures safe transit and protection for international shipping.
Widely used in the process flow of industries such as chemical, petroleum, pharmaceutical, food, and environmental protection, it is particularly suitable for handling highly corrosive and high-temperature fluid media, such as various acid-base solutions, organic solvents, corrosive gases, etc.
