PTFE butterfly valve is an industrial valve with polytetrafluoroethylene (PTFE) as the core material, designed for highly corrosive, high temperature, or high purity media environments. Its unique structure and material properties make it widely used in chemical, pharmaceutical, water treatment, food processing, and other industries, especially for occasions requiring strict sealing and chemical erosion resistance.
Mostly stainless steel or all PTFE material, lightweight design to reduce fluid resistance.
PTFE or enhanced PTFE (such as adding glass fiber, carbon fiber), wear resistance, and excellent elasticity.
Support a bi-directional pressure seal to ensure that the valve does not leak under both positive and negative pressures.
