Electric fixed ball valve
The Electric Fixed Ball Valve is a high-performance automated valve designed for reliable flow control and shut-off in industrial pipeline systems. It features a trunnion-mounted fixed ball structure combined with an electric actuator, providing stable operation, excellent sealing performance, and long service life under high-pressure and large-diameter applications.
Unlike floating ball valves, the fixed ball design uses upper and lower stem supports to reduce operating torque and improve mechanical stability, making it ideal for demanding applications involving high pressure, large flow rates, and continuous operation.
Equipped with an electric actuator, the valve enables remote automatic control, precise positioning, and integration with industrial control systems such as PLC and DCS. It is widely used in oil & gas, petrochemical, power generation, chemical processing, and other industries requiring safe isolation, automated operation, and reliable pipeline control.
