Manual Butterfly Valve: Purely Mechanical Operation
Manual butterfly valves are like traditional faucets, relying entirely on manual rotation of the handle or gears to open and close the valve. The characteristics of this type of valve are:
No Power Required: Opening and closing is achieved solely through a mechanical structure.
Simple Structure: No complex circuitry, low maintenance costs.
Suitable Scenarios: Atmospheric pressure pipelines, temporary projects, or outdoor environments with limited power supply.
Electric Butterfly Valve: Automated Control
Electric butterfly valves are a product of modern industry. Their core differences are:
Requires Wiring: The built-in motor requires a 220V or 380V power supply.
Remote Control: Can be connected to a PLC system for automated management.
Intelligent Adjustment: Some models support precise flow control and status feedback.
Selection Requires Considerations
When choosing a butterfly valve, consider three main dimensions:
Control Precision: Choose electric for frequent adjustments, manual for occasional opening and closing.
Installation Environment: Electric is preferred if power is available and remote control is required.
Budget Cost: Electric valves are typically 3-5 times more expensive than manual valves.
