Pneumatic valve and female pneumatic valve flange their respective advantages and disadvantages?

Pneumatic valve and female pneumatic valve flange should be how to choose I believe that many companies unit at the time of design piping should be to consider a problem.
now that we have to consider is to choose the pneumatic valve, pneumatic valve flange is internal thread then we must first understand the pneumatic valve and female pneumatic valve flange their advantages.


pneumatic valve flange advantage is:
1. Some convenient disassembling in the pipeline, suitable for medium and large chemical project.
2。 Resistance to acid and alkali stability, resistance to pressure ability strong, durable in use.

the flange of the pneumatic valve disadvantages:
1. High cost, large volume, installation time, generally need two completed two or more persons. Selection is usually DN15 - DN25 caliber.

the advantages of internal thread pneumatic valve:
1. Small volume, convenient installation, generally applicable to domestic outfit building, or steam pipes and other small pipes.
2。 Cheap, low cost for factory unit. Internal thread of the pneumatic valve disadvantages: damage is not easy to tear open outfit, especially fixed the pipe. Continued weak under pressure. General selection is below (pipe specification.

together, pneumatic valve and female pneumatic valve flange each have advantages and disadvantages, customers can choose according to their actual usage is suitable for the use of the working principle of both are the same, the difference is the flange prices higher than female pneumatic valve, pneumatic valve size is bigger.
