Cast steel lined PTFE flange globe valve is a valve body made of carbon steel WCN casting. The internal passage and valve plate are lined with anti-corrosion materials such as PFA, FEP, PTFE, PO, etc. Fluorine lined flange globe valve is usually a low channel inlet medium and a high channel outlet medium (low inlet and high outlet medium mode). The rising valve stem drives the valve plate to open the valve. When the valve stem descends, it needs to overcome the resistance of the pipeline medium, so more force is required. Fully lined fluorine flange globe valve is suitable for use in pipelines with strong corrosive media and high pressure working conditions
