Flanged shut-off valve 15nzh22nzh – a device in which the locking element moves forward in a direction parallel to the direction of the liquid in the pipeline. Due to the fact that it can be fixed in intermediate positions, its loss is not only a function of a locking, but also a regulating flow mechanism.
