Whether used in high or low-temperature conditions, this ensures stable opening and closing torque, ensuring process continuity.

Production

Flanged Butterfly Valve Production Process

Raw Material Selection

Each flanged butterfly valve body material (such as ductile iron, carbon steel, and stainless steel) undergoes chemical composition analysis and mechanical property testing to ensure that the raw materials meet the requirements.

Processing

By casting or forging the flanged butterfly valve body and then performing precision machining and processing, the flange surface is effectively flattened, reducing the flow resistance of the Hearken Flow flanged butterfly valve disc.

Overall Assembly

After raw material testing, the sealing materials and components undergo a series of finishing processes before being assembled.

Overall Inspection

Hearken Flow flanged butterfly valves undergo relevant performance testing after each process step and after final assembly. These tests include visual inspection, five-village inspection, airtightness testing, water pressure strength testing, and life testing.
