When gas pressure is admitted to\u00a0the tester, it acts on the full area of the valve bellows to lift the stem\u00a0off the seat. When this pressure increased, the stem tip lifts further\u00a0off the seat. By using the valve probe tester, an accurate measure of\u00a0the stem tip travel, per pressure increase, can be determined and\u00a0the results tabulated and plotted.<\/p>\n<p>When the pressure is plotted as the ordinate and the stem tip travel\u00a0as the abscissa, a relatively straight line will be generated for the\u00a0majority of the stem tip travel. The slope of this line is an indication\u00a0of the &#8220;stiffness&#8221; of the valve. The numerical value of the slope is\u00a0called the bellows assembly load rate (blr) and is measured in\u00a0psig\/inch [kpa\/mm]. In this context, the &#8220;bellows assembly&#8221; includes\u00a0the bellows and the system which applies a load to hold the valve\u00a0stem on the seat. The higher the load rate, the \u201cstiffer\u201d the valve and\u00a0inversely, the lower the load rate, the \u201csofter\u201d the valve.<\/p>\n<p>If the above is done with the same valve, except that opening\u00a0pressure (dome charge or spring setting) is varied, then the effect of\u00a0dome charge pressure or spring setting on the bellows assembly\u00a0load rate can be compared for the same type of valve when set for\u00a0different opening pressures. The bellows assembly load rate is a\u00a0practical value that can be used to compare different types of valves\u00a0or when evaluating the same valve under different load conditions\u00a0and when designing the gas lift installation.[\/vc_column_text][vc_btn title=&#8221;Download PDF&#8221; style=&#8221;custom&#8221; custom_background=&#8221;#305f72&#8243; custom_text=&#8221;#ffffff&#8221; shape=&#8221;square&#8221; align=&#8221;left&#8221; i_icon_fontawesome=&#8221;fa fa-file-pdf-o&#8221; add_icon=&#8221;true&#8221; link=&#8221;url:http%3A%2F%2Fparveen.in%2Fwp-content%2Fuploads%2F2019%2F10%2FGATE-VALVE.pdf|||&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_gallery interval=&#8221;3&#8243; images=&#8221;2634&#8243; img_size=&#8221;full&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;2\/3&#8243;][vc_column_text]The purpose of the gas lift valve probe tester is to determine the\u00a0relative &#8220;stiffness&#8221; of a gas lift valve and to determine the maximum\u00a0available travel of the stem top.
