standard bore for gate valves
standard bore for gate valves
(OP)
Hello,
Please consider this example:
I have a P&ID with a 2" gate valve. I have no equipment data sheet on this valve. It is not stated to be full port.
What i want to know is what is the valve area.
My question is :
Is there a standard bore size for gate valves? For example a 2" gate valve, will have a xxxxx " opening?
Many thanks,
jon

RE: standard bore for gate valves
To answer your question: I don't think so. However, it might be that for a certain manufacturer, a standard 2" gate valve would always have the same size opening.
Two things to consider: 1) Contact the specific manufacturer and ask; 2) Next time you take the valve apart, measure the opening

RE: standard bore for gate valves
If you’re looking for the minimum port openings allowed, refer to the following standards:
For valves manufactured to API 600 (generally cast valves, flanged and butt-weld, like is made by Crane Valve)
API 600, Sect. 5.3.3.1, Table 4, Minimum Port Diameters.
For valves manufactured to ANSI/API 602 (generally small forged valves, threaded, socket-weld and flanged, like is made by Vogt)
ANSI/API 602, Sect. 5.2, Table 1, Minimum Diameter of Equivalent Flow Passageway.
