Finding valves – protective reinforcement of pipelines, which is designed to prevent the ability to move in the back of the working environment in the highways. Such valves are necessary in emergency situations when the pressure of the medium in the highway is sharply reduced, or in the combined pipelines, to protect the pumping equipment of individual pipelines. The valves can be installed both on horizontal areas and on vertical, since they can perform their function thanks to the spring, which ensures the shutter.
Flight valves are reliably mounted on pipelines through the flange connection. Shooting device – spool or ball element, in the check valves it moves perpendicularly or back to the stream, reliably overlapping it. Ball check valves (flange) are often installed in plumbing pipelines on small pipes.
