Installation requirements for a 64-kilogram gate valve with a DN40 diameter
Thread Content
It is a gate valve with a pressure rating of 64 kilograms, a DN40 diameter, made of super duplex steel; it is connected to the pipeline by socket welding. Is support required for the valve when it is installed vertically?
Small-bore hand valves do not require support, in any direction.
It’s better not to use welded valves if it’s not necessary. Inspection, maintenance, and repair are very troublesome.
High-pressure valves are often welded to reduce leaks at the flanges.
I know. However, a design pressure of 64 kilograms is not very high, and the flange can fully meet the requirements. If the medium is non-toxic and harmless, there is no need for welding. Check the requirements in the design institute’s drawings.
