PFA lined Diaphragm Valve


PFA-lined diaphragm valve

This product uses a special process to coat the valve body with PFA/FEP, and the diaphragm parts use PFA/FEP and EPDM, so that the various parts of the valve cavity can achieve the same corrosion performance. The product has good throttling characteristics, corrosion resistance and granular media properties, reliable sealing performance, and can be widely used in various corrosive fluids and fibrous and powdery media.



Size:DN15~250

Features:The diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve disc and other parts above the diaphragm are not corroded by the medium, the packing sealing structure is omitted, and the medium leakage will not occur.
