Vertical lifting cast steel lined PTFE flange check valve, also known as one-way valve or check valve; The rise of the valve core through the medium causes the valve core to fall and seal when the medium flows back. Its main function is to prevent the backflow of the pipeline medium, which may cause some equipment failures and damage. The valve body of the product is made of carbon steel WCB casting, with a unidirectional design of the valve core inside. The valve core, like the passage, can be lined with PTFE material, usually FPA, FEP, PTFE, etc., to isolate the erosion of strong corrosive media.
