Valve sealing surface

Can a soft seal be used in high-pressure situations? For example, in the case of 16 MPa, is the soft seal made of polytetrafluoroethylene? Seeking advice from an expert
High pressure can be handled using soft seals, as well as PTFE, PEEK, etc
As long as the temperature is not high, soft-sealed versions can be used; the materials for soft seals include PTFE/reinforced PTFE, etc
It is recommended to use semimetallic gaskets; it seems that non-metallic gaskets are not suitable for high pressures. Check the general guidelines for selecting petrochemical equipment or standards such as SH equipment standards, HG20592, etc.
In areas with high pressure, it also depends on the application; it’s best to have a threaded connection, or to use it in places such as pressure gauges with a M20*1.5 thread for measurement.
