High frequently operated ball valve (average 300,000 cycles per year and even more than 1.6 million cycles annually) is widely used in chemical industry where frequently on/off operating is needed, especially at PDS (Products Discharge System) unit in PP (polypropylene) or PE (polyethylene) plant. Antiwear has done lots of research on sealing surface metal alloy coating which can meet frequently operating application based on plenty of testing and experiments. Besides that, optimizing structural design and manufacturing process takes themetal-seated ball valve a long service life of up to 3 million cycles, which would be the best choice for high-frequently operating applications.
