A clean-out valve is installed at the pump outlet
Thread Content
If the pump’s outlet diameter is 100 or less, what size should the drain valve at the outlet be? Is there any standard for this?
Manual for the Installation Design of Process Piping in Petrochemical Plants – Part 1: Recommended values are provided in the design and calculation sections; for pipes with a diameter of DN100, a valve with a diameter of DN25 is sufficient
Although we are not aware of the specific specifications, here we generally use DN100, with a 25mm vent valve as standard.
As a general rule, valves with a diameter of DN15–DN25 are usually sufficient.
I only know that it is usually DN20 or DN25; I’m not sure where this comes from. The 2nd floor is great!
