- Butterfly Valve Product Catalog
- Butterfly Valves are quarter-turn valves which employ center-mounted circular flaps that swing into, and out of, the flow stream. Key specifications include port connection, valve size, and the materials that make up the valve body, its seat, seal, disc, and stem packing. Butterfly valves are used in wastewater plants, power plants, and process plants for shut-off and for regulating and isolating service and are especially popular in very large diameter pipelines. Generally smaller and cheaper than a ball valve of the same capacity, butterfly valves can be difficult to operate against high pressure and flow. They are also more leak-prone than ball valves and subject to higher head losses.
