Our bronze butterfly valves (also known as butterball valves) are U/L Listed and FM Approved for use in a sprinkler system. They are typically found on riser manifold assemblies and have been designed with a slow close hand wheel operator, which reduces water hammer. These butterball valves feature minimum flow restriction and pressure loss when they're fully open.
