Electric ball valves are pivotal in modern automation systems, offering precise control and reliability in fluid and gas handling applications. These valves combine the simple design of a traditional ball valve with the advanced control capabilities of an electric actuator, making them indispensable in various industries, including manufacturing, water treatment, and HVAC systems.

Design and Functionality

At its core, an electric ball valve consists of a spherical ball with a hole through its center, which controls the flow of fluids or gases. The ball is positioned within a valve body and can rotate 90 degrees to open or close the passage. The “electric” aspect of the valve comes from the actuator, which is an electric motor responsible for turning the ball to the desired position. This integration of electrical control allows for remote operation and automation, enhancing the valve’s functionality compared to manual versions. The actuator itself is equipped with a motor that drives a gearbox, which in turn rotates the ball. Most electric ball valves are designed with feedback mechanisms, such as limit switches or position sensors, to provide accurate position reporting and ensure that the valve is fully open or closed. This feedback capability is crucial for maintaining system integrity and ensuring that processes run smoothly.
