Q:Valve and ball valve is the same thing? Don't know don't speak: Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves

Q:What's the diameter of the 4 point ball valve?: 4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.

Q:The difference between ball valve q41f46-16c and q41f46-16: There is no difference. If the latter model is P, then the stainless steel flange lining fluorine ball valve, the former is cast steel material.Q41F46-16C is the type of ball valve, cast steel flange lining fluorine ball valve!

Q:What does "q41f46-16c-dn40" mean?: DN40 refers to the nominal diameter, 16C represents 16 kg of pressure, carbon steel material F46 stands for fluorine

Q:How to distinguish between single and double ball valve?: I don't know what you mean by "single" and "double", but the ball valve can be divided into one, two and three.

Q:Electric ball valve installation need to pay attention to what?: 8, electric and pneumatic valve in order that no special contract allows only vertically installed in the indoor use. 9, after the completion of the pipeline construction, all the valves on the pipeline line shall be opened and the residual dirt shall be removed.

Q:What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?: (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.

Q:Calculation formula of ball valve flow: The sectional area of diameter of DN15, DN25 and DN50 is respectively:DN15:15*3.14/4=176.625 mm, 0.0177 square decimeter.DN25:25*3.14/4=490.625 mm, 0.0491 square decimeter.DN50:50*3.14/4=1962.5 mm, 0.1963 square decimeter.A pipe flow rate of V=4 M / s V=40 decimeter / s, and the 1 liter =1 cubic meter, the pipe flow respectively (cross-sectional area multiplied by the velocity):DN15 pipe: flow Q=0.0177*40=0.708 L / sec,It's 2.55 cubic meters per hour.DN25 pipe: flow Q=0.0491*40=1.964 L / sec,It's 7.07 cubic meters per hour.DN50 pipe: flow Q=0.1963*40=7.852 L / sec,It's 28.27 cubic meters per hour.Note: a flow rate must be given to calculate the flow rate, which is calculated in accordance with 4 meters per second.

Q:Where to buy the ball valve?: Use less to the local hardware market, use more direct to find a company to buy

Q:What does the sealing surface of the ball valve stand for HF?: HF is the abbreviation of two English words: "Hard Face", which means surface hardening. Usually surfacing is made of Tailai alloy (Alloy 6). Other surface hardening methods include hard chromium plating. This method is used more in the ball valve. But hard chromium plating is prone to small cracks, which reduces its corrosion resistance.
