Question:

Stem V type PTFE packing maximum pressure /?

Stem V type PTFE packing maximum pressure /?

Answer:

The valve packing VTa is a normal cryogenic valve with a set of V type low leakage graphite packing!Valve stem: the valve stem is not only moving parts, force components, but also seals when the valve is opened and closed.

At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing. Therefore, in selecting the stem material, it must be guaranteed that it has sufficient strength at the prescribed temperature, good impact toughness, scratch resistance, corrosion resistance.

The valve stem is a vulnerable part, and the mechanical performance and heat treatment performance of the material should be paid attention to when selecting.
