Click to zoomPTFE Lined Butterfly Valve
Two pieces of body butterfly valve adopt a concentric disc and seat configuration with a complete PTFE sealed structure. The body undergoes a complete package PTFE painting process. The painting thickness can reach up to 3-4mm, effectively preventing the direct interaction between the body and the medium and the corrosion of the body by the medium.
