Stainless steel lifting flanged check valve 16nzh10nzh Pn 16

Stainless steel flanged check valves 16nzh10nzh made PN 16 are lifting check valves that are used to prevent backflow of the working medium in pipelines. The main purpose of the valves is to protect the system from damage caused by the reverse movement of the medium, which can occur with sudden pressure drops.

Operating principle

• When the working medium is supplied, the spool rises due to the flow pressure and opens the passage.
• When the supply of the medium stops or a backflow occurs, the spool returns to its original position under the action of its own weight, hermetically blocking the flow.

Installation and operation

Valves 16nzh10nzh are installed on horizontal pipelines with the cover facing up. When installing the valves, it is necessary to ensure that the flanges are installed without distortions and coincide with the holes in the pipeline. The valves should be installed on sections of the pipeline accessible for inspection and maintenance.
