Are there any special requirements for the valves on the vacuum pipeline? Can ordinary PN2.0MPa ANSI valves be used permanently?

It only needs to be able to withstand vacuum; the other requirements are the same as those for ordinary valves

When purchasing valves, specify the vacuum requirement, whether it is a full vacuum or a semi-vacuum.
