Valve coatings

Now standard for the Flowserve McCANNA McCannaseal top-entry wedge-seated ball valve, the Tungsten carbide and thermal-spray coatings offer cost savings through reduced maintenance and increased resistance to abrasive, high-temperature and severe-service applications. The coatings are applied using various methods including chemical vapor deposition process (CVP) and thermal spray. In laboratory testing, Flowserve found that the coating technologies increased cycle life by approximately 150% under severe operating conditions. www.flowserve.com
