Fisher control valve flow calculator
WebJun 29, 2012 · C1= Cg /Cv . How can I calculate C1? And what variables do I need? Thanks in Advanced TD2K (Chemical) 29 Jun 12 18:38 Cg is a term only used by Fisher I believe. You will need to get one of their catalogues and look for the valve you are using. WebIf we were to graph this table, plotting flow versus stem position, we would obtain a very linear graph. Note how 50% open gives us twice as much flow as 25% open, and 100% open nearly twice as much flow as 50% open. This tells us our control valve will respond linearly when operated under these conditions (i.e. operating with a constant pressure …

Webflow stream velocity. Gas flowing through a control valve experiences an acceleration as it approaches the vena contracta. Fig-ure 13-1, showing the velocity profile super-imposed over a pressure profile, illustrates how the velocity increases and decreases passing through a valve. High noise levels can be generated even though the outlet WebSimplistically, if it can be guaranteed that the steam leaving a control valve is superheated, then 250 m/s is an appropriate limit to place on the outlet velocity. Sometimes, when saturated steam is supplied to a control …
