What does Lb mean? It’s a term related to valves; what does it signify?
It should be a pound-based unit, with a number in front of it, right?
There is a number in front; for example, 600LB. Could you be more specific?
Lb means pounds. Its meaning is: the pressure exerted by a pound of mass under the force of gravity on an area of one square inch. 1 pound = 0.4536 kilograms, and 1 inch = 25.4 millimeters. Therefore, 1 lb = 0.4536 × 9.8 / (0.0254 × 0.0245) = 6890 Pa. Thus, 150 lb is approximately equal to 1 MPa. However, in valves, CL150 lb corresponds to 2 MPa
1 pound per square inch (psi) = 0.006895 megapascals (MPa) = 0.0703 kilograms per square centimeter (kg/cm2) = 0.0689 bars = 0.068 atmospheres (atm). Kilograms (kg), Megapascals (MPa), Pounds per square inch (Lb): 202150, 505300, 636.3400, 10010600, 15015900, 250251500, 33733.72000, 420422500.
