| Belzona Repairs Butterfly Valve Gasket | | | Industry:General Industry (GIND) | | | Application:Gaskets, Seals and Shims (GSS) | | | Customer Location:MO, USA | | | Application Date:September 2006 | | | Application Situation:The customer scheduled a maintenance outage to build the gasket with the Belzona elastomer for the butterfly valve to prevent delay with reinstalling. | | | Problem:The butterfly valve from the main circulating water system of the power plant was removed for maintenance and required a new gasket prior to reinstallation. | | | Products:Belzona 2131 (D & A Fluid Elastomer) | | | Substrate:Cast Iron and Steel | | | Application Method:The application was carried out in accordance with Belzona Know-How System Leaflet GSS-1 using Belzona 2131. After grit blasting the surface, heavy gauge wire was used to form a channel to apply Belzona 2131 to the proper thickness. | | | Belzona Facts:The Belzona solution was less than the cost of the OEM gasket, but was chosen more to alleviate the difficulty of positioning the valve back in-line below the surface of the river with a separate, loose gasket which could easily lead to mechanical damage and/or improper sealing. | | | Photographs Description
