Electric Actuated Trunnion Mounted Ball Valve
- Electric Actuation, Remote Control: Equipped with a high-performance electric actuator, enabling automated, remote control and precise position adjustment of the valve, enhancing operational efficiency and safety.
- Low Operating Torque: Trunnion-mounted design with the ball supported by bearings significantly reduces friction between the ball and seats, allowing the electric actuator to drive the valve with lower torque.
- Reliable Sealing Performance: Features a spring-loaded floating seat design, ensuring tight contact between the seats and the ball, providing stable and reliable bidirectional sealing.
- Suitable for High Pressure & Large Diameter: The fixed ball support ensures less stress on the seats, making it particularly suitable for severe high-pressure and large-diameter applications.
- Double Block and Bleed (DBB): Features Double Block and Bleed function, allowing for pressure relief in the valve cavity, enhancing pipeline maintenance and operational safety.
- Automatic Pressure Relief: If the pressure of the retained medium in the valve cavity rises abnormally, the seats automatically retract to relieve pressure, protecting the valve and pipeline.
The Electric Actuated Trunnion Mounted Ball Valve is a high-tech product that combines the excellent performance of a trunnion-mounted ball valve with the automated control capabilities of an electric actuator. Its core design features a ball precisely supported by upper and lower trunnions, ensuring low operating torque and reliable sealing performance in various high-pressure, large-diameter applications. Equipped with an electric actuator, this valve enables remote automated control, precise regulation, and rapid opening/closing, significantly enhancing operational efficiency and safety. It is particularly suitable for industrial processes requiring a high degree of automation and frequent operations, such as in oil & gas, chemical, power generation, and water treatment industries.
