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.
