Industrial ball valves are shut-off devices in-charge of regulating the flow of liquids or gases via a rotating ball placed with a hole. By turning the ball 90 degrees around the axis, the valve either opens or closes, allowing the medium to pass through or not to when blocked.
One of the most useful types of this valve is the trunnion-mounted ball valve. Trunnion-mounted ball valves are more preferred for high-pressure applications needing a tighter, safer seal. They are used for industrial processes, as well as for electricals. Wondering about which companies out there can provide these valves? Read on.
