Butterfly Valve Manufacturer
Reliable Sealing Performance
The butterfly valve of Hearken Flow adopts a combination of a three-eccentric structure and an anti-corrosion elastic sealing seat. The mating surfaces of the butterfly plate sealing edge and the sealing ring are precisely polished and ground, and the uniform clamping force design is used to effectively eliminate leakage gaps. You can choose EPDM, FPM, NBR, Viton, PTFE, rubber and other chemically resistant sealing materials according to working conditions to meet the sealing adaptation of different media characteristics.

Easy Installation And Maintenance
Hearken Flow’s butterfly valve adopts standard modular design, and the sealing material is corrosion-resistant and aging-resistant. The valve stem seal is not easy to deform under long-term operation, and the phenolic back seat is used, which will not fall off and is resistant to stretching. Hearken Flow provides you with a variety of connection methods including wafer type, flange type, butt welding type, socket welding type, threaded type, lug type, clamp type, quick release type, etc. to adapt to different pipeline types, making your installation and maintenance easier.
Production
Butterfly Valve Production Process
As one of the leading high performance butterfly valves manufacturers, Hearken Flow provides versatile solutions including the high performance butterfly valve for demanding industrial environments. We are the trusted butterfly valves manufacturers for global projects.
Raw Material Inspection
Before processing, all raw materials undergo chemical composition analysis and mechanical testing. We strictly verify material grades (e.g., SS316, SS304) to guarantee corrosion resistance and structural integrity in your specific operating environment, preventing premature failure due to material defects.
