1 inch ball valves are compact quarter-turn valves designed to control the flow of liquids or gases in small-diameter pipelines. They use a rotating ball with a central bore to provide quick, reliable shutoff and minimal pressure drop when fully open. These valves are well suited for low- to high-pressure applications where precise flow control and tight sealing are required. Common applications include residential and commercial plumbing, water supply lines, irrigation systems, compressed air lines, HVAC systems, and light industrial process piping.
