What are the ways to choose butterfly valves

When choosing a butterfly valve, the following aspects can be considered:

1. Working conditions: First of all, we must understand the working conditions of the butterfly valve, including media, temperature, pressure, etc., and ensure that the selection of the butterfly valve meets these conditions.

2. Valve size: According to the pipe size and flow requirements, choose the appropriate butterfly valve size to ensure smooth flow.

3, material selection: according to the nature of the medium to choose the butterfly valve material, common materials are cast iron, carbon steel, stainless steel and so on. If the medium is corrosive, you can choose a special material butterfly valve.

4. Sealing performance: The sealing performance of the butterfly valve directly affects the service life and leakage of the valve. Butterfly valves with double or triple eccentric structures can be selected to improve sealing performance.

5. Operation mode: Select manual operation or automatic operation butterfly valve as required. Manual operation is suitable for smaller pipes, while automatic operation is suitable for larger systems that require frequent flow control.

6. Accessories selection: Select appropriate accessories according to needs, such as position indicator, manual operation device, electric device, etc., in order to better control the operation of the butterfly valve.
