Check valves rotary
The valve is the reverse pivot is one of the models of check valves, which work item (disk) has a rotation axis located perpendicular to the axis of the pipeline. Such valves may be called the reverse pivot sliding Windows. All valves of this type, always set immediately after standing pump unit. Thus he protects it from possible water hammer. Rotary valves are used in a wider range than other various modifications of check valves. They are produced to the desired diameter DN2200 mm and up to the highest pressure PN400 kgf/cm2. Depending on various operating parameters of the system, its environment work environment temperature and the temperature of the environment in which they are installed, these valves can be distinguished by the material production casing is stainless steel, cast iron, steel, not metal, bronze, brass and titanium. In their connection the valves are divided as follows: on a wafer, flanged, socket and butt weld.
In systems which are designed for pressure up to 25 kgf/cm2 the greatest distribution was obtained wafer opposite rotary valves which are made of cast iron. Their great advantage is a little weight. This fact greatly simplifies their installation in the pipeline.
