The operating principle of an electric stainless steel ball valve can be summarized as follows: the electric actuator provides driving force and rotates the ball to control pipeline flow. USA VTON combines a stainless steel ball valve with an electric actuator to provide automated pipeline control.
1. The Electric Actuator Receives a Control Signal
When the control system sends an open or close command, the actuator receives the signal and starts operating. Depending on the configuration, the actuator can provide on-off control or valve-position control.
The actuator should therefore be matched with the valve’s operating torque and the control system requirements.
2. The Actuator Rotates the Ball
A ball valve contains a ball with a flow passage. The electric actuator rotates the valve stem, which changes the position of the ball.
When the ball passage aligns with the pipeline, the medium can pass through. When the ball rotates to the closed position, the passage is shut off.
For modulating applications, the actuator can change the ball position according to the control signal, adjusting the effective flow area.
3. Position Feedback Supports Automation
For remotely managed systems, position feedback can transmit the actual valve status to the control system. Operators can therefore issue commands while also monitoring valve position or open-close status.
USA VTON electric stainless steel ball valves can be configured according to control and feedback requirements.
Application Example
At a certain industrial process pipeline, automatic switching of process media was required. An electric stainless steel ball valve was used for pipeline control. The control system sent operating commands, the actuator rotated the ball, and feedback signals were used to confirm valve status.
Operating Advice
When selecting an electric stainless steel ball valve, the valve and actuator should be considered as a complete system. Do not select the actuator based only on nominal pipe size. Medium, pressure, temperature, operating frequency, valve torque, and control requirements should all be evaluated.
