Problem

OEM supplied bonnet gasket on Class 150# and 300# Crane Gate Valves is typically a thin corrugated metal gasket.As these valves age, the flange face surfaces deteriorate over time and create sealing problems when attempting to use these type gaskets.

Solution

The solution is to use a flexible graphite sheet gasket or a graphite faced metal gasket. The graphite provides a far superior sealing surface due to its ability to flow into flange imperfections.
