Applications
It is suitable for industrial valves and pumps applications in power plants, petrochemical operations and refineries at high temperatures. Not suitable for use with strong oxidisers, combustion gases and airflows over 450°C. If used with harder wiper rings it can be used for dynamic applications. If not the valve’s pressure should be kept under 100 bar.
