Larox wafer knife gate valves for fly ash application

Release date 06/09/2011

NRG Big Cajun Power Plant in Ventress, Louisiana, USA, has bought DN 300 Larox wafer knife gate valves to its fly ash application. Big Cajun II comprises three coal-fueled steam units, which generate 1,700 megawatts of baseload or load-following generating capacity.

Customer used to have problems holding a tight seal with their knife gate valves before. The cavity at the bottom of the valve was getting jammed up with material from the flowing medium. They purchased two Larox knife gate wafer valves and installed them early this year. The customer has been very satisfied with the performance and has since put three more Larox knife gate valves on order for this application.

Larox Heavy Duty Wafer Knife Gate Valves are built with a cast body and features a heavy-duty stainless steel gate. Removable seats on either side of the blade provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry. LKW is available with pressure rating up to 10 bars.

Headquartered in Lappeenranta, Finland Larox Flowsys Group has subsidiaries in Linthicum, Maryland (USA), Sydney (Australia), Johannesburg (South Africa) as well as in Kouvola (Finland).
