Nonreturn valves

Check valve - a type of Valve, the principle of operation of which is to ensure the movement of the working medium in one direction, and prevent movement in the opposite direction.
Depending on the tasks, it can be used as a locking element:
- bullet;
- disk;
- membrane;
- -spool.
Check valves operate independently under the influence of gravity based on the differential pressure in the pipeline. Usually, it is made of carbon or stainless steel, brass, polypropylene.
