Hi all,
I have a job I need to recommission that has Crane valves, specifically D930 model double regulating type (they are branded "John" which I understand was a local Australian company that licensed them to sell in Australia at one stage about 20 years ago). I cant find any data on the internet about them. Does anyone have any graphs for these or can tell me what type of valve they are? The Crane website has a D931 which seems to be a fixed orifice double regulating valve, is that what the D930 was/is? If that is what it is then I guess all I need to know is the KV value of the valve, ie you don't need a set of graphs right?
Thank you for any help on this, I am really in a world of pain if I cant get a hold of any data for it.
Cheers
