Manual Butterfly Valve: A Complete Analysis of Economical Fluid Control Equipment
The Manual Butterfly Valve is an ideal choice for low-cost fluid control systems due to its simplicity, low cost and ease of operation. In this article, DELCO Valve will share its multi-scenario applications, selection suggestions and maintenance tips.
Structure of Manual Butterfly Valve
Manual butterfly valve is mainly composed of valve body, valve shaft, valve plate, sealing ring, actuator and so on. The valve body is the main part of the manual butterfly valve, connecting the two ends of the pipeline. The valve shaft is an important part to support the valve plate, connecting the valve body and the valve plate. The valve plate connects to the valve shaft and controls the flow and pressure in the pipeline by virtue of its rotation. The valve plate is connected to the spindle and controls the flow and pressure in the pipeline by its rotation. The sealing ring is located in the groove around the valve plate and prevents fluid leakage by contacting the valve body after compression. The opening and closing of a manual butterfly valve is controlled by an actuating device (e.g. a handle).
Working Principle
Manual Butterfly Valve realizes the opening and closing control of fluid by rotating the butterfly plate driven by the handle. The angle between the butterfly plate and the pipe determines the flow rate, which is suitable for quick adjustment and shut-off operation.
Multi-scenario Application
- Agricultural irrigation: Manual Butterfly Valve is suitable for agricultural irrigation system, which is economical and practical, and helps to control the water flow accurately.
- Domestic water supply: In low pressure water supply system, it is used for quick opening and closing and flow adjustment, easy for daily operation.
- Industrial back-up: The Manual Butterfly Valve can be used as a manually operated back-up solution in the event of automated valve failure.
- Marine Engineering: Corrosion-resistant design butterfly valves are suitable for seawater environments, providing reliable fluid control.
Core Advantage
- Simple structure: handle-driven design, easy to install and use.
- Inexpensive: Ideal for budget constrained projects.
- Various materials: cast iron for conventional media, stainless steel for corrosive media, PVC for lightweight requirements.
How to Choose the Right Manual Butterfly Valve
- Material selection: cast iron, stainless steel or PVC according to the characteristics of the medium.
- Handle design: Ensure that the handle length is suitable for the operating environment and easy to use.
- Pressure Rating: Select the matching pressure rating and valve size according to the working environment.
Installation and Maintenance Recommendations
- Correct installation: Ensure the correct position of the butterfly plate in the pipeline to avoid leakage caused by improper installation.
- Regular lubrication: Keep the bearings and seals lubricated to prolong the service life of the equipment.
- Troubleshooting: If there is any problem of handle jamming or water leakage, check the wear and tear of the butterfly plate and seals.
Conclusion
Manual Butterfly Valves are widely used in agricultural, domestic water supply and industrial standby systems due to their low cost and high efficiency. Through correct selection and maintenance, the effectiveness of its use can be significantly improved.
