Marine Diving Solutions Demolished the existing stem, stem guides, stem guide brackets and gate utilizing an 80-Ton crane. The new rising stem knife valve was installed with EPDM rubber gaskets at each flange and all new stainless-steel bolts were installed. The new 1-1/4' diameter stem is stainless steel. The stem guides are cast steel, anchors are mild steel, all stainless-steel hardware, bronze bushings, and steel collars with epoxy paint. The new low-flow knife gate valve was operated and reported that it functioned smoothly.
