Q: What are the valves at home?: Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.

Q: What does "TD671F" mean?: You should type is wrong, or I should be D671F, with very limited knowledge and scanty information, this type of mean (D) pneumatic butterfly valve (6) of the clip (7) sealed the middle (1) fluorine plastic (F). There should also be a number of pressure figures and body material. For example, D671F-10C later means that the pressure is 10 kilograms (or 1.0MPa) and C represents the carbon steel

Q: How to quickly identify the types of valves?: You can look through shapes, signs, or buy a valve manual

Q: Is the valve galvanized?: If you need it, you can order it. Any valve will do

Q: What are the valve types H, F, and Y? What are the meanings of these 3 letters?: Please refer to "JB/T308-2004 valve model preparation method"Sealing surface material codeH Cr13 stainless steelF fluoroplasticY cemented carbide

Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?: Well, it's not easy. And you do not give the specific structure of the valve, so there is no way to talk about the calculation. The simplest way is to install the pressure gauge and the flow meter on both ends of the valve, and read the data directly.

Q: What does valve DN50/80 mean?: Hello landlord DN50 valve refers to the valve diameter of 50mm DN80 is 80mm if the valve is opening and closing function, so the valve diameter should be and pipeline with the diameter or smaller number, large waste, butterfly valve to be stuck in the flange, the influence of flow.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two, such as 57mm pipe with DN50.

Q: What does "DN15" mean? What does "PN 16" mean?: Valve nominal diameter 15mm, valve nominal pressure 1.6MPa

Q: What items and detailed procedures should be inspected for valve size inspection?: Valve body structure length and flange size, GB size, the implementation of GB/T12221-2005. American Standard. (the American Society of mechanical engineers ASME B 16.10-2000).
