The cast steel lined PTFE direct current flange globe valve is a valve body made of WCB carbon steel material, with corrosion-resistant materials such as PFA, FEP, PTFE as the lining of the valve passage in contact with the medium, thereby isolating the medium from corroding the metal valve body. The fluorine lined direct current globe valve is designed for direct current, with a larger flow channel and lower resistance, making it more suitable for use in corrosive media with high flow requirements.
