Q:What is the difference between wafer (flangeless) type and LUG type of butterfly valves?

WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand

Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?

Front is the same, there is C refers to the body of the material is carbon steel, without C, usually refers to gray iron (cast iron is more common, so are generally omitted)

Q:That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!

I know there are automatic fire fighting systems and the oil industry.

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.

Q:Where are the exhaust valves, mud valves and butterfly valves?

The exhaust valve is used for the heating of the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.Mud valve, also known as cover valve, commonly used in urban water plants, sewage treatment plants sedimentation tank bottom discharge sludge.Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.

Q:How many kinds of butterfly valves are there?

What's the score?There are central butterfly valve, double eccentric butterfly valve, three eccentric butterfly valveAnd according to the materialAnd according to the way of connection

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

well depends .. how far the piston was down and if the valve is still in the valve guide. intake you may have to pull the intake and feed it up from the intake port .. exhaust .. pull the manifold and feed it back up from the exhaust port.. and last .. pull the head .. if the the valve is still in the guide and the piston is not at the top .. you may could turn the engine slowly by hand to the top the piston may push up the valve up . you may be able to pull the valve up then..

Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?

The clamp and flange are the two connections.The clip type is cheaper and the price is approximately 2/3 of the flange.The length of the clip type valve bolt is longer, and the requirement of construction accuracy is higher. If the flange on both sides is wrong, the bolt will be subjected to greater shearing force, and the valve will leak easily.

Q:What's the difference between D71X-16 and D71H-16 butterfly valves?

D71X-16 and D71H-16 butterfly difference is that the cut-off is not the same, the latter is stainless steel seal, corrosion resistance, friction, acid or impurities can be medium fluid. The former is rubber sealed, only through the general temperature of the medium, not acid, with more, you can ask Luoyang crown Ning

Q:The difference between the directly buried gate and the flange valve and butterfly valve

The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
