What is the Appropriate Term for the Contacting Surface on a Valve in the U.S.?

AI Thread Summary
The discussion centers on identifying the correct term for the contacting surface on a valve in the U.S. The user describes a joint between the valve body and bonnet, highlighting the sealing surface that resembles an annulus. Suggested translations from Russian include "sealing girdle" or "sealing band," but the user is seeking a commonly accepted term in English. "Seal face" is proposed as a potential term, which seems to resonate with the participants. The consensus leans towards "seal face" as the most appropriate terminology.

Contact surface -- term

Hello everyone!
Help me please with selecting a correct term.
The situation is as follows:

There is a valve, which has a body and a bonnet.
There is a joint that connects the body to the bonnet.
There is a contacting surface on the bonnet flange and body flange that is used for sealing the inner cavity of the valve.
This surface looks like an annulus, or a ring and we have the area, inner diameter and outer diameter of it.
If translated from Russian it may sound as "sealing girdle", or "Sealing band".
Could it be "seal face"?

Could you please name the term that is used in the U.S.?
Hope, I made myself clear.

Thank you!

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
