DN80 PTFE Liner Stainless Steel Wafer Butterfly Valve

• The material selection of stainless steel wafer butterfly valve in accordance with relevant standards, and refuses to cut corners.
• Standard structure,Thick casting,Quick and light opening and closing, convenient maintenance.
• Strong corrosion resistance: The PTFE liner butterfly valve is not easily eroded by corrosive media such as acids and alkalis, so it can maintain the service life of the valve body.
• Application fields: PTFE liner butterfly valve is not only suitable for liquid media, but also suitable for fluid control in various working conditions such as gas and steam.
• Good stability: PTFE lining can fix the internal rubber and prevent it from deforming during use.
• PFA (polytetrafluoroethylene copolymer) has excellent chemical and heat resistance, making it suitable for spraying in harsh environments. This coating remains stable at high temperatures and has good wear and corrosion resistance.
• Double stem butterfly valve: Allow more medium traffic to pass, reduce flow resistance and reduce pressure drop.
• polished stainless steel disc: Stainless steel valve plate polishing can not only improve the gloss and beauty of the surface, but also enhance the corrosion resistance and wear resistance of stainless steel. It can also reduce pollution caused by stainless steel surface corrosion.
