Different Butterfly Valves Include Pneumatic, Electric And Manual

Feb 19, 2024 | News

Butterfly valves are essential components in industrial applications, offering efficient flow control. Choosing the right type of butterfly valve depends on various factors. These factors or saying features include the desired driving mode, working pressure, working temperature and structural features. Firstly, Pneumatic actuator butterfly valve offer reliability and versatility, with the choice between wafer and flanged designs. Meanwhile, electric butterfly valve provide automated operation and precise control, making them suitable for a wide temperature range. In addition, Manual butterfly valves offer simplicity and cost-effectiveness, ideal for low-pressure applications. Consider your specific requirements and application needs to select the most suitable butterfly valve type for your industrial processes.

I. Pneumatic Actuator Butterfly Valve: Reliable and Versatile

Characteristic: Wafer or Flanged Butterfly Valve

  • Pneumatic actuator butterfly valves can be either wafer or flanged in design.
  • The choice between the two depends on the specific application and installation requirements.

Work Pressure: Mid-Pressure (2.5MPa < Pn < 6.4MPa)

Pneumatic actuator butterfly valves are designed to handle mid-pressure applications. So it provides reliable performance and efficient flow control.

II. Electric Butterfly Valve: Automated and Precise

Driving Mode: Electric

  • Electric butterfly valves are powered by electric actuators.So, It enables automated operation and precise control over fluid flow.
  • This driving mode eliminates the need for manual intervention. This isideal for applications requiring remote control or frequent adjustments.

Working Temperature: Normal Temperature (-40°C < T < 120°C)

Electric butterfly valves can operate within a wide temperature range, from -40°C to 120°C. Meanwhile, wide range of working temperature makes them suitable for both hot and cold applications.

Structure: Double-Eccentric Sealing

  • Electric butterfly valves feature a double-eccentric sealing structure, which enhances sealing performance and reduces wear and tear on the valve seat.
  • This design ensures tight shut-off and minimizes the risk of leakage.

III. Manual Butterfly Valve: Simple and Cost-Effective

Driving Mode: Manual

Manual butterfly valves are operated manually, either through a lever or a handwheel.

This driving mode offers simplicity and cost-effectiveness, making them suitable for applications where automation is not required.

Structure: Center Sealing

Manual butterfly valve typically feature a center sealing structure, providing reliable sealing performance and ease of operation.

Work Pressure: Low Pressure

Manual butterfly valves are designed for low-pressure applications, offering economical flow control solutions.

Stem Material: Stainless Steel

The stem of manual butterfly valves is commonly made of stainless steel, ensuring durability and resistance to corrosion.
