What is the pressure drop of a swing check valve?
Thread Content
On the oil and gas recovery system, a check valve is installed at the outlet of the fan. I’m wondering what the pressure drop of the gas-phase check valve is approximately; does anyone know? It would be great if there were screenshots from reference books available.
It’s listed in the manufacturer’s sample for this valve. If not, ask this manufacturer.
You might as well measure the actual value using your existing check valve to see what the resistance is; it should be pretty accurate. It’s just ordinary pressure calculation.
It also has to do with the horizontal and vertical installation.
For gas-phase media, and especially when it is only an outlet short tube, the pressure drop at this location can be practically ignored!
The weight of the valve disc should be taken into account, right?
I don’t have any samples here. Do you have the manufacturer’s contact information? Could someone provide it?
