Vacuum Service Valves
Service envelope language used in Chinese and ASME/GB catalogues. Class is not a substitute for the nameplate and the standard.
What this node is for
Vacuum Service Valves is a service-envelope word (pressure or temperature). PN, Class, vacuum or “high temperature” still need a numbered standard, a body material and a seat/packing schedule in the RFQ.
KanBeng does not treat this page as a stocked equivalent list. If no model rows are published yet, describe the duty in an RFQ rather than waiting for a table to appear.
