Chinese valves are classified by pressure

Chinese valves are classified by pressure:

There are many ways to classify valves in China. Today, TJL indusry group introduces you to the most common classification of valves: valves are classified into the following five valves according to the nominal pressure. I hope to help you purchase Chinese valves. For high quality Chinese valves, please contact: Info@tjlindustry.com

(1) Vacuum valve: refers to a valve whose working pressure is lower than the standard atmospheric pressure.

(2) Low pressure valve: refers to the valve with nominal pressure PN ≤1.6Mpa.

(3) Medium pressure valve: refers to the valve with nominal pressure PN of 2.5Mpa, 4.0Mpa and 6.4Mpa.

(4) High pressure valve: refers to a valve with a nominal pressure PN of 10.0Mpa to 80.0Mpa.

(5) Ultra high pressure valve: refers to the valve with nominal pressure PN≥100.0Mpa.

The above is the classification of the five valves that TJL indusry group summed up for you. We will give you a detailed introduction to other classifications of Chinese valves in the future.
