一、进口对焊式金属硬密封蝶阀产品概述

进口对焊式金属硬密封蝶阀（美国威盾VTON），Welded metal hard seal butterfly valve，也叫焊接式蝶阀，手动焊接蝶阀，涡轮焊接蝶阀，焊接双偏心蝶阀，焊接硬密封蝶阀，是指采用焊接结构，使阀门与管道连接达到永久性的零泄漏的蝶阀，无需使用法兰，对管道的保温起到良好的效果，因此适用于供暖、供热，治金、电力、石油化工等工业管道上，作调节流量和载断流体使用。

Welding metal hard seal butterfly valve (VTON), also known as welding butterfly valve, manual welding butterfly valve, turbine welding butterfly valve, welding double eccentric butterfly valve, welding hard seal butterfly valve, refers to a butterfly valve that adopts a welding structure to achieve permanent zero leakage connection between the valve and the pipeline. It does not require the use of flanges and has a good insulation effect on the pipeline. Therefore, it is suitable for industrial pipelines such as heating, heating, metallurgy, power, petrochemical, etc., for regulating flow and carrying fluid.
