FAQ

How do you calculate the flow of the valve?

Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.

What are the key valve enterprises in China? Mainly in those areas?

The region, the largest number of Wenzhou. Focus on the valve business, Zhongyuan District Kaifeng high pressure valve factory, Zhengzhou Zheng butterfly valve on behalf of the butterfly valve. Shanghai region, Tianjin, northwest Lanzhou high pressure, Suzhou area, northeast Tieling region, Dalian, Shenyang and so on. And the Zigong area

Where is the Shandong valve? How about joint valves in Shandong?

To find Shandong valve manufacturers, Shandong better valve manufacturers are in Weifang, find the valve factory is also simple, direct search "Weifang valve" is

What's the name of the valve?

This is not a valve, it is a pipe bender.

1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise

It should be said that the diameter is represented by units per inch! 15mm 6mm nominal diameter valves representing metric units!

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)4. [case]Galvanized steel pipe DN50, sch 20Galvanized steel pipe "NB2", sch 205., the outer diameter and DN, NB relationship is as follows:------DN (mm), --------NB (inch), -------OD (mm)15-------------- 1/2--------------21.320--------------3/4 --------------26.725-------------- 1, ----------------33.432-------------- 1, 1/4, -----------42.240-------------- 1, 1/2, -----------48.350-------------- 2, -----------60.365-------------- 2, 1/2, -----------73.080-------------- 3, -----------88.9100-------------- 4, ------------114.3125-------------- 5, ------------139.8150-------------- 6, ------------168.3200--------------- 8------------219.1The above data is referenced only in ASTM A53. Please note that there are some differences in external diameter with different specifications.
