Electric Trunnion Ball Valve

ALIS Valves offers Electric Trunnion Ball Valves for industrial applications requiring reliable pipeline isolation, automated operation and dependable performance under demanding pressure conditions. These valves feature a trunnion-mounted ball supported at the top and bottom, helping maintain stable ball positioning and reduce excessive loads on the valve seats during operation. The ball rotates to align its bore with the pipeline for flow or turns to block the passage for shut-off. An electric actuator drives the ball according to control commands, enabling remote operation and integration with programmable logic controllers (PLCs), distributed control systems (DCS) and other industrial automation platforms. Depending on the application, the valve can be configured with suitable body and ball materials, seat arrangements, stem sealing and pressure-rated components to meet the required process conditions.

Electric Trunnion Ball Valves are used in oil and gas pipelines, refineries, petrochemical plants, natural gas processing facilities, power generation units and other industrial fluid-handling systems. Depending on the selected materials, pressure class and sealing configuration, they can be specified for compatible liquids and gases within their rated operating limits. Important selection factors include valve size, working pressure, operating temperature, process media, body and ball materials, seat design, leakage requirements, end connection standard and operating torque. Buyers should also consider the actuator’s electrical supply, control signal, operating time, duty cycle and required open-close or modulating function. For critical applications, fire-safe qualification, anti-static features and stem blowout protection should be verified where required. Selecting the appropriate valve and electric actuator combination helps support dependable shut-off, convenient remote operation and reliable performance under the intended working conditions.
