When selling and using industrial valves, the term \"LB\" is often mentioned in reference to the valve’s pressure rating. The common unit used abroad is lbf/in2 (pounds per square inch), while in China the standard unit is Mpa (megapascals). Based on this, valve pressure ratings are classified from low to high as follows: 6, 10, 150, 300, 400, 600, 900, 1500, 2000, 2500, etc. Correspondingly, in terms of Mpa, these ratings correspond to values of 2.0, 5.0, 6.3, 10.0, 15.0, 25.0, 33.7, 42.0. These represent the corresponding pressure ranges; it is not necessary to convert between LB and Mpa.
