一、进口美标球阀概述

进口美标球阀（美国威盾VTON），American Standard Ball valve，也叫API球阀，ANSI球阀，美国石油标准球阀，是指球阀的设计制造标准是API 600、API 602，在管路中主要用来做切断、分配和改变介质的流动方向的球阀。美标球阀的工作原理是靠旋转阀恋来使阀门畅通或闭塞。球阀开关轻便，体积小，可以做成很大口径，密封可靠，结构简单，维修方便，密封面与球面常在闭合状态，不易被介质冲蚀，在各行业得到广泛的应用。

American Standard Ball Valve (VTON), also known as API Ball Valve, ANSI Ball Valve, or American Petroleum Standard Ball Valve, refers to a ball valve designed and manufactured according to API 600 and API 602 standards. It is mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. The working principle of American standard ball valves is to rotate the valve to make the valve unobstructed or blocked. Ball valves are lightweight, small in size, and can be made into large diameters. They are reliable in sealing, have a simple structure, and are easy to maintain. The sealing surface and spherical surface are often in a closed state, and are not easily eroded by media. They are widely used in various industries.
