Product Description
The Advantages of Single Flange Butterfly Valve Compared to Wafer Butterfly Valve and Flange Butterfly Valve
1. Compared to Wafer Butterfly Valve
Although the single flange butterfly valve and the wafer butterfly valve have the same structural length, in terms of installation method, the single flange butterfly valve is bolted to the pipe flange. The single flange butterfly valve has many bolt holes and the connection is more stable.
2. Compared to Double Flange Butterfly Valve
- Lower price: Single-flange butterfly valve has only one flange. Compared with double-flange butterfly valve, the material cost and manufacturing cost are lower, so the price is more economical and affordable.
- Smaller space occupied: Single flange butterfly valve has only one flange connection. Compared with double flange butterfly valve, the overall structure is simpler and takes up less installation space.
- More convenient installation: Single-flange butterfly valves only require one flange connection. Compared with double-flange butterfly valves, the installation process is simpler, saving time and effort.
- Wider scope of application: Single flange butterfly valve can be applied to some simple pipeline systems, especially for situations where one side is fixed.
