Butterfly valve and ball how to distinguish from the appearance
- To say the difference, the biggest difference is that the butterfly valve is a piece of open and close, and the ball is a ball. They work by spinning their own axes!(1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;(2) butterfly valve structure is relatively simple, low pressure general use butterfly valve, butterfly valve the maximum pressure can only reach 64 kilograms. Ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.(3) butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric three, the eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg;(4) the valve can also be divided into soft seal and seal, soft seal valve can reach the highest temperature below 280 degrees, the pressure is below 64 kilograms, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms.s

What is the difference between ball valve and plug valve?
- The main advantages of plug valves are as follows:Suitable for frequent operation, quick and easy opening and closing.Fluid resistance is small.The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance.Good sealing performanceFree from the direction of installation, the flow direction of the medium can be arbitrary.No vibration, little noise.Plug valve installation and maintenance should pay attention to the following matters:Leave the valve handle in a rotating positionCannot be used as throttling.s
What is the force distance of a ball valve with a diameter of 150mm?

Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ
- For example, the relationship between CF8M and F316.Natural gas pipelines look at bore, pressure, temperature, and composition.Clean natural gas with ordinary carbon steel ball valve on the line.Material basically A105N, LF2 based.As for pipes, I don't need to forge steel. My suggestion is that they should be made of forged steel.s
