    Ball valve vs Globe valve for On-Off application

    Hi, Can anyone confirm which one is better option for shutdown applications i.e globe valve or ball valve? As per my understanding , ball valve act fast as well as economical as compared to globe. Is leakage across ball valve is more than globe valve?

    Primary Flow Element Accuracies

    Hi, I have a doubt related to accuracy of flow orifice , flow nozzle and venturimeter. As per my understanding, these all are restrictive devices, so pressure drops across orifice , flow nozzle and venturi are considered as 0.1 bar, b/w 0.05 and 0.1 bar , 0.05 bar respectively. How the accuracy...

    Restriction Orifice

    I have a query related to restriction orifice. Since, restriction orifice is not bevelled at downstream of it.So, does it work in both directions i.e bidirectional. For eg if we are using RO for preventing reverse flow. If downstream pressure exceeds because of back flow, will it kill that extra...
