Q:What does 3/4''mean in the name of the valve?

Valve diameter, that is, we often say 6 points valve, used in English units, with metric units should be DN20.2 points DN84 points DN156 points DN20 (3/4'')1 inches DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN1005 'DN1256 'DN1508 'DN20010 'DN25012 'DN300Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.Because the units have metric (mm) and British (inch) distinction, there are the following methods of address.1., based on the metric system (mm), called DN (metric unit)2., on the basis of the British system (inch), called NB (inch unit)DN (nominal, diameter)NB (nominal, bore)OD (outside, diameter)

Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.
