5. FAQ
1. What is manual wafer butterfly valve?
Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Butterfly Valve?
Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.
3. What is the working principle of manual wafer butterfly valve?
A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q:i have a slightly small mitral valve leak in my heart. my cardiologist say nothing to worry about, but i am not sure. can some one explain if it would eventually lead to some complications?
- I have Mitral Valve Prolapse, and slight regurgitation. If your cardiologist says not to worry, I wouldn't worry. Mitral Valve prolapse just means you have a slight deformity of the bicuspid valve. It doesn't close correctly. It's not a disease, or anything like that, just a slight deformity. The symptoms are annoying. You may or may not have palpitations, slight sharp chest pain sometimes, dizziness, fatigue, and anxiety from it. You must have it checked yearly to make sure it's not progressing. I have had it since I was born, and now I am 28, and it has not progressed at all. MILLIONS of people are walking around with it, and don't even know it. It's not really a big deal. However, it does have the potential to worsen and you may or may not need a new valve. But that normally happens when you're older, in your 50's or up. Don't worry about it.
- Q:Which is more expensive, gate valve or butterfly valve?
- Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.
- Q:Types of butterfly valves
- There are clip on butterfly valves and flanged butterfly valves,Manual, pneumatic, electric,
- Q:How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks
- save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar
- Q:Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
- Simply the engine size and the number of cylinder, the 3.0 has 6 the 2.3 has 4, however both engines have four valves per cylinder(2 intakes 2 exhaust) and dual overhead cams(dohc)
- Q:Does the pneumatic butterfly valve need electricity?
- Are pneumatic, and directly rely on gas control, the most important thing is that the gas, then certainly have to take control of electricity!
- Q:I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.

- Q:Butterfly valve model D344H and D343 difference
- In fact, almost all refers to the sealed variable eccentric butterfly valve.1, D344H-10C DN4002, D343H-10C DN400Let's talk about the similarities between the 2 Butterfly models: D stands for butterfly valves, 3 represents turbine drivers, and the middle 4 represents flanged connections,10 represents the pressure of 10 kg, C represents the butterfly valve, the material is cast steel, and DN400 stands for the caliber of the valve;To say that where there are differences between the 2 models, there is a place where there are differences, second means 4 of the first models is the new type sealing valve structure is variable eccentric, second of the second models of the 3 represents the structure of the valve is three eccentric, and three eccentric seal variable eccentric type is in fact a meaning.Sealed three eccentric butterfly valve, sealed variable eccentric butterfly valve, corresponding to the central butterfly valve and sealed single eccentric butterfly valve.
- Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
- Their models are different, the structure is different, they are the main driving part, different worm gear and straight rod distinguish, all belong to the flange valve.
- Q:Butterfly valve is generally used in what position?
- Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, environmental protection, chemical smelting and power building water supply and drainage engineering system in conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
