<dc:description xml:lang="pl"><![CDATA[The results of the investigation of the prototypical ball valve are presented in this article. The innovation of the tested valve is a ball with a built-in measuring orifice. The valve has been subjected to durability tests. Leakage under three temperatures: ambient, -30 degress C and +100 degress C was analyzed. Sealing elements of the valve were tested for roughness and deviation of shape before and after the cycles of operation.]]></dc:description>
<dc:description xml:lang="pl"><![CDATA[Ball valve operation means cycles of open/close. It was planned to perform 1000 cycles at each temperature condition accordingly. Tests of the valve were performed under gas pressure equal to 10 MPa. The research was carried out under the Operational Program "Intelligent Development" (POIR 01.01.01-00-0013 / 15 "Development of devices for measurement of media flow on industrial trunk-lines".]]></dc:description>
