Motorized Butterfly Valve
The motorized butterfly valve is operated for opening and closing by an electric motor drive. Its main features include electric control, simple operation, fast response speed, high reliability, etc.This actuated butterfly valve with electric actuator is suitable for application scenarios that require precise control and remote operation, and can provide efficient and reliable fluid control solutions.
Motorized butterfly valves mainly include the follwoing types:
- Wafer Type Butterfly Valve: It has a simple design, small footprint, and light weight, and provides two sealing methods: elastic sealing and metal sealing.
- Flanged Butterfly Valve: It adopts a vertical plate design to ensure the stability of the valve. The sealing ring adopts a composite design of a flexible graphite plate and a stainless steel plate to enhance the sealing effect.
- Welded Butterfly Valve: It is suitable for high-temperature and high-pressure environments, and is especially suitable for fields such as building materials, metallurgy, mining, and electric power.
- Grooved Butterfly Valve: A speed reducer is added to the design to enhance the operating performance. It is suitable for large-diameter occasions and is sturdy and durable.
- The mounting pad of the motorized butterfly valve is designed as per ISO 5211. It is easy for the user to configure the standard electric actuator by himself;
- The upper and lower stem is designed for anti-blow out. This design prevents the risk of a blowout when maintenance is required;
- 3. The seal is designed for fire safety. Sealing is not resilient seated and can meet API 607 fire test requirements;
- 4. The torque is low. Users can match a lower gear than the conventional electric actuator, saving costs.
- Overloading protection keeps the valve and your project safe
- Multiple control methods for choice
- Weather-proof protection class which suitable for outdoor uses
- ISO 5211 mounting standard which could suitable for all types of a butterfly valve
- Available in adjusting the open/close angle to make the flow control more easily
- Strict quality control with ISO9001:2015 to ensure a low failure rate of the actuator
- Provide wafer/lugged/flanged/tri-clamp butterfly valves to meet your pipeline requirements.
- Large size range for choice and that could meet your pipeline size.
- Easy installation and easy maintenance. Long service life span.

- Power Industry: In thermal power plants, electric butterfly valves are employed in cooling systems, condensate systems, etc., to regulate the flow and pressure of water and guarantee the normal operation of equipment.
- Chemical Industry: They are widely used in the transportation and control of various chemical fluids, such as acid, alkali, and salt solutions.
- Oil and Gas Industry: During oil extraction, refining, and transportation, electric butterfly valves control the flow of fluids like crude oil and natural gas, ensuring the safe and stable operation of pipelines.
HVAC Systems
- Air – Conditioning Systems: In central air – conditioning systems, electric butterfly valves regulate the flow of chilled water and hot water to achieve precise control of indoor temperature.
- Ventilation Systems: In ventilation ducts, electric butterfly valves control the flow and pressure of air, enabling the adjustment of the air volume in the ventilation system.
Food and Beverage Industry
- Beverage Production: During beverage production, electric butterfly valves control the flow of raw materials such as water, fruit juice, and syrup to ensure the quality and taste of products.
- Food Processing: In food processing, electric butterfly valves control the flow of fluids like edible oil, milk, and sauces to meet the requirements of different processing technologies.
Environmental Protection and Water Treatment
- Water Treatment Systems: In various water treatment systems, electric butterfly valves are used for flow control and pipeline connection.
- Flue Gas Desulfurization and Denitrification: In the flue gas desulfurization and denitrification systems of enterprises such as thermal power plants and steel mills, electric butterfly valves control the flow of desulfurizers, denitrifiers, and other fluids to ensure the flue gas meets emission standards.
How to size electric actuated butterfly valve actuators?
To size electric butterfly valve actuators, first, determine the torque required to operate the valve. This depends on factors like valve size, pressure difference, and the type of fluid. Then, consider the operating speed and duty cycle needed. Manufacturers usually provide torque-speed curves and specifications. Match the calculated torque and other requirements with the available actuators, choosing one that can provide sufficient torque and meet the operational demands while allowing for some margin of safety. Also, take into account the power supply available and any specific environmental conditions.
