Product Overview
WUYI's PTFE-lined corrosion-resistant control valves use high-pressure injection molding for all media-contact surfaces, lined with PTFE for excellent corrosion and aging resistance. Suitable for acids like hydrochloric, sulfuric, nitric, and hydrofluoric acid, the valve also features a PTFE bellows seal. It is widely used in process control involving strong corrosive, toxic, or volatile gases and liquids.
