We recently sent out an order of very highly specified Weir Type diaphragm valves. Our customer is heavily engaged in chlorine services and required a valve that would provide very high internal and external corrosion resistance.
Internal corrosion protection is provided by ETFE lining and our triple layer Grade 9R diaphragm (TFM /PVDF/EPDM), fitted with a titanium insert (see news story below). Xylan coated fasteners and a stainless steel hand wheel provide excellent external protection against the harsh environmental conditions the valves will experience.
