Low-temperature short-axis cut-off valve Manufacturers china introduces to you what is a low temperature cut-off valve? What is the selection principle?

1. It is advisable to choose a stop valve on the pipeline or device of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high temperature and high pressure pipelines in petrochemical systems.

2. On pipelines that do not require strict flow resistance. That is, where the pressure loss is not considered much.

3. Needle valves, instrument valves, sampling valves, pressure gauge valves, etc. can be used for small valves.

4. There is flow adjustment or pressure adjustment, but the adjustment accuracy is not high, and the diameter of the pipeline is relatively small, such as the pipeline with a nominal diameter of ≤50mm, it should be selected.

5. Small and large chemical fertilizers in synthetic industrial production should use high-pressure angle stop valves or high-pressure angle throttle valves with a nominal pressure of PN160 and a nominal pressure of 16MPa or a nominal pressure of PN320 of 32MPa.
