阀组的描述

IV30和IV31型三阀组
三阀组由两个阻断阀和一个压力补偿阀组成。阻断阀将过程与测量仪表（如压力表、开关或变送器）分开。压力补偿阀可确保压力补偿在⊕面和面之间，避免在调试和操作期间发生单边过压。

IV50和IV51型五阀组
与三阀组相比，五阀组配有两个额外的排放阀。单边压力排放阀可确保操作人员进行单边压力排放，此外还可进行双边压力排放。

阀组主轴头不可旋转，以减轻密封元件的磨损。这样也可显著延长产品使用寿命，尤其在频繁开启和关闭的情况下。

阀采用防爆设计，可改善其工作安全性，尤其是在高压负荷的情况下。

威卡（WIKA）可将阀和压力测量仪表***装配在一起，并将这一服务与其他附件纳入到直接安装的解决方案中，这也被称为连接。为确保整个系统的工作性能，在进行连接时也会进行泄漏测试。
