Issues regarding the standard dimensions in valve design
Thread Content
Is there a model of gate valve with an external dimension of 210mm? Our company has a gate valve of type Z45T-16 (L), whose structural length is 210mm; it now needs to be replaced. After checking all relevant standards and documents, it was found that all models of this type have a length of 229mm. Why is that?
Is it maybe custom-made, or isn’t this model included in the standard list?
If it doesn’t work, cut it off and replace it with another flange!
**Indeed, there is no structural dimension of 210mm in the American standards
For now, the idea is to machine short flanges on lathes or work on PE pipelines
@2887848: Go out and clean the floor; move it to the valves – this might help resolve the issue more quickly.
The length of valves produced by some manufacturers may deviate from the standards, so many valve manufacturers indicate that the structural length is in accordance with their own standards; it is necessary to pay attention to this length when installing piping. If a valve replacement is needed, it is best to contact the manufacturer for confirmation.
