Ball Valves

Ball valves give you a straightforward way to turn the flow of water or other compatible fluids on and off with a quarter-turn handle. Inside the valve, a ball with a hole through its center rotates to open or close the flow path. On most manual ball valves, a handle lined up with the pipe signals an open valve, while a handle turned across the pipe signals a closed valve. These shutoff valves can help isolate sections of a plumbing system for maintenance around the farm, barn, shop or house. Whether you’re planning a livestock watering line, an irrigation connection or a general water supply project, choosing the right ball valve starts with checking the application, pipe size and connection type. Match the valve’s pressure and temperature ratings to your system, and check that it’s approved for the fluid it will carry rather than assuming every water shutoff valve fits every job. Finding the right ball valves also means paying attention to flow needs and installation space. A full-port ball valve has an opening close to the pipe’s inside diameter, which helps limit flow restriction, while a reduced-port design has a smaller opening that can create more resistance. Check the valve specifications to see which design makes sense for your plumbing or irrigation system, and leave enough clearance to move the handle through its full turn. For drinking water lines, look for the applicable potable-water certifications and lead-free compliance; fuel gas and compressed air systems need valves specifically rated for those applications. Ball valves generally work best for fully open or fully closed service, rather than frequent fine adjustments to flow. Before installation, shut off the supply, relieve system pressure and follow the manufacturer’s directions for joining and sealing the connections. A properly selected shutoff valve puts flow control within easy reach and can make the next repair a little less of a chore.
