Butterfly valves are quarter-turn valves, they open and close whenever the operator turns 90 degrees. They’re space-efficient and cost-effective compared to other valve types.
General butterfly valves are constructed with elastomer that are susceptible to erosion, high-performance butterfly valves use resilient material like graphite to seal the seat.
High performance butterfly valves can handle everything that general service butterfly valves can process, but they’re made to withstand the liquids and gases general service valves can’t tolerate. They can handle chemically reactive and corrosive liquids, gases and steam. You can find high-performance butterfly valves made with carbon steel, stainless steel, and other metals. The metals are welded so that the valve can withstand temperatures as low as -320 degrees F and as high as 1200 degrees F, and endure pressure levels up to 1440 PSI.
No matter what type of vicious material you’re processing, you can find a high-performance butterfly valve that caters to your needs. If your application runs a risk for fugitive emissions, you can use a high performance butterfly valve that features stem seal extensions for leak-proof emissions control. If your pipes process extremely cold temperatures, you can find high performance butterfly valves with pressurized neck extensions that allow for pipe insulation.
High-performance butterfly valves are the best option for power generation applications, such as energy power plants. They’re also the safest way to go for petroleum refineries and any chemical processing applications involving reactive chemicals. Water treatment plants should also opt for high-performance butterfly valves to cope with high water pressure levels.
Whether you go with a general service butterfly valve or high-performance one depends on whether or not a general service butterfly valve is enough to handle the job. You can save money using a general service butterfly valve because it costs less, but you’ll end up with losses if it’s not able to handle the demands of your application. To select the right butterfly valve for your application, make sure you take into account the viscosity, temperature and pressure levels of the materials you’ll be processing.
