China Electric Double Flanged Butterfly Valve 380V - Durable, High Torque, Remote Control | Trusted Suppliers & Factory
The main features and advantages of the electric butterfly valve
The electric actuator enables precise positioning of the valve plate, which is beneficial for regulating the flow. This level of precision is crucial for energy conservation, product quality, and production safety.
Remote operation and monitoring through an automatic control system reduce manual labor and enhance efficiency.
One of the significant advantages of the electric butterfly valve is its remote operability. The actuator allows operators to adjust the valve position from a distance through the control system. Especially in large industrial facilities, emergency manual operation is impractical.
Due to the lightweight valve disc and low torque, the electric butterfly valve consumes less power, which can save energy and costs.
Types of electric butterfly valves
Butterfly valves with switch-type actuators: These actuators are designed to fully open or fully close the valve. They are typically used in applications requiring binary flow control for sufficient capacity.
Regulating actuators: Regulating actuators can precisely control the valve position, allowing the valve to be set at any position between fully open and fully closed. This feature requires a reliable butterfly valve; otherwise, it could damage the valve plate.
In addition, there are some other parameters for the electric actuator:
Waterproof type: The waterproof level is usually indicated by the ingress protection (IP) rating. For example, an IP67 rating indicates that the actuator is dustproof and can withstand brief immersion in water, while an IP68 rating indicates that it can withstand continuous immersion in water. The waterproof motor usually uses corrosion-resistant materials such as stainless steel or coated metals to extend its service life in humid environments.
Explosion-proof type: It is specifically designed for hazardous environments where there are flammable gases, vapors, or dust. It prevents internal sparks or heat from igniting the surrounding explosive environment. The actuator housing is made of sturdy materials such as cast iron or aluminum with a thick wall, which can contain any internal explosion and prevent it from entering the external environment.
