自力式调节阀是一种无需外加驱动能源,依靠被调介质的压力或温度为动力源及其介质变化,按设定值,进行自动调节的节能型控制装置。它集检测、控制诸多功能于一阀,自成一个独立的仪表控制系统。 自力式调节阀采纳了标准模块化的设计。我们的产品具有标准化、系列化、通用化的特点,三化水平高。 自力式压力调节阀和差压调节阀的部件具有互换性,如果控制条件改变,可以便捷地更改弹簧和膜头部件。
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.
