What Are the Main Types of Brass Ball Valves? Brass ball valves are quarter-turn shutoff devices that use a rotating ball with a bore to control fluid or gas flow. The short answer: there are six primary types — full port, standard port (reduced port), two-way, three-way, mini ball valves, and multi-turn ball valves —...
View MoreThe Direct Answer: Another Name for a Ball Valve The most widely recognized alternative name for a ball valve is the quarter-turn valve. This term comes directly from how the valve works: a 90-degree rotation of the handle is all it takes to fully open or fully close the flow path. Beyond that single label, ball valve...
View MoreThe Short Answer: How a Ball Valve Should Be Installed A ball valve should be installed with the handle or actuator in an accessible position, the flow direction aligned with the valve's design (bidirectional for most standard ball valves), proper thread sealant or gaskets applied, and all connections torqued to the m...
