Q: Transformer butterfly valve and pressure relief valve difference: The butterfly valve is usually fitted with an oil immersed transformer between the tank and the radiator to control the flow of oil between the transformer tank and the heat sink. When large power transformers are delivered, the radiators are usually individually packed to reduce transport sizes. The butterfly valve is closed to prevent the outside air or water from entering the transformer tank. When the transformer is transported to the installation site, the radiator is installed on the butterfly valve one by one. When the radiator is installed, the butterfly valve can be opened so that the oil flow between the transformer, the oil tank and the radiator can be circulated, so as to play the role of heat dissipation.When the transformer is running, it is found that when the radiator has seepage, the butterfly valve can be closed to avoid further leakage of transformer oil, and a new radiator can be replaced.

Q: In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?: Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.

Q: Butterfly valve is the control valve?: The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.

Q: Butterfly valve general use occasions: Valve is especially suitable for low differential pressure, large diameter, large flow of gas and slurry liquid. For general control valve, DN300mm is big valve, only individual to DN450, and for the butterfly valve, DN500 below is a small valve, DN500 ~ 1000 is the standard valve, the largest butterfly caliber up to 9m. Visible, large diameter pipe with the main butterfly valve.

Q: How does the pneumatic butterfly valve control the angle of opening?: This is really not good, control seems to be pneumatic defects, can only rely on the feeling

Q: i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II: Your going to have to pull the heads.

Q: Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.: Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.

Q: valve adjustment 2001 chev prism 1.8L: valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.

Q: e.g. a patient with a prosthetic aortic valve and a patient with a prosthetic mitral valve. Also, can you get stenosis of mechanical valves or just tissue grafts?Thanks!: mechanical okorder /

Q: 1988 volkswagon cabriolet, rabbit tried mystery oil let sit for a week having trouble with stuck valves even taken a wrenrch to manually unstick. help any suggestions 4 cyclinder car has been sitting up for about 4 years: The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
