目前,多数液压阀品种均以球墨奥盖尔液压泵配件作为阀体主要材质。液压阀阀体主要零件的材质,首先应考虑到工作介质的物理性能(温度、压力)和化学性能(腐蚀性)等。同时,还应了解介质的清洁程度(有无固体颗粒)。除此之外,还要参照国家和使用部门的有关规定和要求。液压阀阀体的材质,种类繁多,适用于各种不同工况。现把常用的壳体材质、内件材质和密封面材质介绍如下。液压阀阀体常用的材质 


1.灰奥盖尔液压泵配件 灰奥盖尔液压泵配件阀以其价格低廉、适用范围广而应用在工业的各个领域。

4.碳素钢(WCA、WCB、WCC)起初发展铸钢是为适应那些超出奥盖尔液压泵配件阀和青铜阀能力的生产需要。但由于萨澳配件阀总的使用性能好,并对由热膨胀、冲击载荷和管线变形而产生应力的抵抗强度大,就使它的使用范围扩大,通常包括了用奥盖尔液压泵配件阀和青铜液压阀阀体的工况条件。适用于工作温度在–29~425℃之间的中高压液压阀阀体。其中16Mn、30Mn作温度为–40~400℃之间,常用来替代ASTM A105。适用介质为饱和蒸汽和过热蒸汽。高温和低温油品、液化气体、压缩空气、水、天燃气等。

7.奥氏体油升PV系列柱塞油泵配件 奥氏体油升PV系列柱塞油泵配件大约含18%的铬和8%的镍。18-8奥氏体油升PV系列柱塞油泵配件经常用来使用在温度过高和过低以及很强的腐蚀条件下作为液压阀阀体和阀盖材料。以18-8油升PV系列柱塞油泵配件为基体加入钼并稍微增加镍的含量,实质上就增加其抗腐蚀能力。用这种钢制造的液压阀阀体可以大量地应用在化工上,如输送醋酸、硝酸、碱、漂白液、食品、果汁、碳酸、制革液和许多其它的化工产品。为了适用高温范围,进一步改变材料成分,在这油升PV系列柱塞油泵配件内加入铌,就是我们所知的18-10-Nb,温度可以用到800℃。奥氏体油升PV系列柱塞油泵配件通常用在很低的温度下也不会变脆,所以用这种材料(如18-8和18-10-3Mo)制造的液压阀阀体很适于低温下工作。例如输送液态的气体,象天然气、沼气、氧气和氮气。适用于工作温度在–196~600℃之间的腐蚀性介质的液压阀阀体。奥氏体油升PV系列柱塞油泵配件也是非常理想的低温液压阀阀体材料。
