一、进口不锈钢对夹式止回阀概述

进口不锈钢对夹止回阀是美国威盾VTON全部材料采用新型耐腐蚀不锈钢（304、316、316L），采用对夹式连接方式的止回阀。可在任何位置的管路上安装，防止介质逆流，其连接方式是利用原有管道两端法兰对夹即可投入运行，其各项指标都优于目前市售的任何一种上回阀。运用范围广泛，凡水、气、油、酸、碱液、氢、氨、特别消防管道等介质均可使用。

The stainless steel clamp check valve is a check valve made of new corrosion-resistant stainless steel (304, 316, 316L) and connected in a clamp style, all of which are used by Weidun VTON in the United States. It can be installed on any position of the pipeline to prevent reverse flow of the medium. Its connection method is to use the flanges at both ends of the original pipeline to clamp and put into operation, and its various indicators are superior to any currently available upper check valve. Widely applicable, it can be used in media such as water, gas, oil, acid, alkali, hydrogen, ammonia, and special fire pipelines.
