进口不锈钢蝶阀产品简介：

德国洛克《DE LOCKE》进口不锈钢蝶阀，Stainless steel butterfly valve，也叫不锈钢法兰蝶阀，不锈钢对夹蝶阀，不锈钢衬氟蝶阀，不锈钢软密封蝶阀，不锈钢硬密封蝶阀，是指采用不锈钢304、316、316L作为蝶阀阀体材质，采用聚四氟乙烯的软密封或者不锈钢硬质合金的一体式硬密封的蝶阀，是一种用来实现管路系统通断及流量控制的部件，已在石油、化工、冶金、水电等许多领域中得到极为广泛地应用。其密封形式多采用密封结构，密封材料为橡胶、聚四氟乙烯等。

Introduction of imported stainless steel butterfly valve products:
Stainless steel butterfly valve imported from Germany Valve, also known as stainless steel flange butterfly valve, stainless steel clip butterfly valve, stainless steel fluorine lined butterfly valve, stainless steel soft seal butterfly valve, stainless steel hard seal butterfly valve, refers to the use of stainless steel 304, 316, 316L as the butterfly valve body material, the use of PTFE soft seal or stainless steel hard alloy integrated hard seal butterfly valve, which is used to realize the on-off and flow control of pipeline system It has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. The sealing structure is mostly adopted, and the sealing materials are rubber, polytetrafluoroethylene, etc.
