In the valve description, what does SPW mean?
Thread Content
I would like to ask the experts here: In the descriptions of valves provided by certain design firms, the term SPW is often used, for example: SPW AISI 316/Graphite, SPW AISI 316/PTFE. What does this term mean? Thank you very much
SPW generally refers to the material of the valve’s sealing components; here, AISI 316 denotes stainless steel, while Graphite and PTFE refer to graphite and polytetrafluoroethylene, respectively, which are used as gasket materials. .
SPW is the abbreviation for SPIRAL WOUND GASKET, which refers to a wound gasket
In front is United Carbonide’s flexible graphite, and then there’s DuPont’s polytetrafluoroethylene. Both are trade names.
Thank you, sir. What could be the three words that make up the full form of SPW? Thank you very much
