Butterfly Valves China Manufacturer Supplies Butterfly Valves In DI And Electric pneumatic Types

The main difference between a DI butterfly valve and an electric pneumatic butterfly valve lies in the mode of operation and control:

Operation: A DI butterfly valve is manually operated, requiring direct human intervention to adjust the valve position. An electric pneumatic butterfly valve, on the other hand, is automated and can be controlled remotely using electrical signals or air pressure.

Control: DI butterfly valves offer simple on/off control or limited throttling control through manual operation. Electric pneumatic butterfly valves provide precise control with feedback.

Application: DI butterfly valves are commonly used in applications where manual control is sufficient and automation is not required. Electric pneumatic butterfly valves are preferred in industrial processes and systems.
