阀门是人类文明发展长河中历史最悠久的产品之一，至今已有几千年的历史。在古代美索不达米亚、古埃及和古罗马，就已经用到最简单的闸阀。 当今社会科学技术突飞猛进，新产品层出不穷，但是阀门仍然是现代社会最基本、最不可缺少的产品之一。无论是在高楼大厦、宾馆酒店、高级别墅、普通公寓、市政、工厂的给排水、供热和供气系统中，还是在农、林、牧、副、鱼的灌溉系统中；无论是在造船工业和冶金工业，还是在化工、医药和食品生产过程中；无论是在油田、煤矿开采、运输、提炼过程中，还是在水电站、火电站和核电站中，阀门都在起着非常重要的作用。 　　如果您希望购买性能稳定，质量优异，值得信赖，尽善尽美的阀门；如果您希望整个管道系统运行稳定，控制灵敏，维护方便，可以考虑采用国内一些大厂家的阀门或是美国阀门，采用美国阀门的购置成本可能会略高一些，但是整个产品使用寿命过程中所耗费的全部使用成本却会比较低，同时，您还可以避免由于采用劣质阀门所产生的精力、时间等方面的难于估量的失。当然我们国内的阀门在很多方面也具有优势，而且成本相对较低。 特别是一些大型的阀门生产厂家所生产的阀门品种已经接近甚至超过了国际{lx1}水平。所以在采购阀门的时候，应该从自身的需求特点出发，选择物美价廉的产品是每一位采购商的初衷。
