Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
Q:What do you mean by "2" and "200 CF8M"?
CF8M is stainless steel, and 2 is caliber 50200 and should also be bore
Q:What's the difference between the knife gate valve and the stop valve?
Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
Q:What kind of valve is gate valve? Is it different from the cut-off valve?
Gate valve is applied to the big diameter pipeline valve, the valve is generally used in small pipe diameter pipeline, their internal structure is different, the valve can not regulate the flow of water, the valve can be. If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.
Q:What are the advantages and disadvantages of flat gate valves?
The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.
Q:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.
Flanges for piping above DN50,DN50 (below) can be made of wire or flange (flange for pressure piping)
Q:What is the standard length of GB steel gate valve?
1, product standardsGeneral purpose valves, flanged connections, iron gate valves, GB/T 12232-2005General requirements for steel valves GB/T 12224-2005"Steel flat gate valves for pipelines" JB/T 5298-91Inspection and test of valves. JB/T 9092-1999Standard for safety evaluation of drinking water distribution equipment and protective materials GB/T 17219-1998
Q:What does gate valve DN200PN160 mean?
DN200 refers to the nominal diameter of the valve, the unit is mm, PN160 refers to the valve tolerance pressure, the unit is 1/10MPa.
Q:Gate valve Z41H-16Q generally used for what place?
It is a standard flanged gate valve with engineering pressure 1.6MPa. Generally used in chemical processes, of course, can also be used for municipal and civil engineering. The valve is generally used for cutting occasions fully open or fully closed, is not suitable for flow regulation.
Q:Stainless steel gate valve DN150 200300 weight, who knows?
The weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.It's not that heavy at all
