1.Manual Wafer Butterfly Valve Description：
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve.
2.Main Features of the Manual Wafer Butterfly Valve
a)Cast hole. Flange connection meet ANSI 125/150# DIN PN10/16 BS4504 PN10/16 in the meanwhile.
b)Soft seat. Replaceable. Increase of service life.
c)Double half shaft without pin.
1. Small in size and light in weight, easy instillation and maintenance. It can be mounted wherever needed
2. Simple and compact construction, quick 90 degrees on-off operation

5.FAQ
1. What is manual wafer butterfly valve?
A: 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?
A: 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.
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.
- Q: I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?
- If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?
- Q: Butterfly valve model D344H and D343 difference
- [1] D344H-10C DN400, D343H-10C DN400, to talk about the 2 types of butterfly valves in common: D on behalf of 3 Representatives is butterfly valve, turbine driven, 4 representative is in the middle of flange, representing 10 kg pressure, C is the representative of the valve material is cast steel, DN400 represents the valve diameter; say that there the difference of 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 type variable eccentric in fact, is 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 are the step i need to do so i can change the valve seals my truck has been smoky.,,, any websites i want todo it myself... 1989 chevy silverado 2500 350 engine 5.7L
- If it only puffs blue smoke when you start it and then burns off after a second then its the valve stem seals that need to be replaced which is common on 350 and 305 engine prior to 1990 and have over 150,000 miles or so. The Chilton repair manual explains the procedure on how to replace these.Now if it smokes all the time then it could be caused by worn out rings on your pistons .
- Q: What is the national standard for clip butterfly valves?
- GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
- Q: I need a valve cover gasket replacement because mine is leaking a tremendous amount of oil. The mechanic says it will cost about $269.00 plus tax. I wanted to make sure this figure was the average since I do not know a lot about cars. My car is a Mitsubishi Diamante 2001.
- The gasket set is probably $ 20, so double that to $ 40..... 270 - 40 is 230, divided by 2 man-hours, which is the usually dealership minimum, gives $ 115 an hour. I DON'T THINK SO !!!! Unless you live in Hawaii where everything is expensive, that sounds steep.... real steep. Dealers around here get like $ 85 an hour, so two hours is 170, plus 40 is 210 bucks; Still killer money for the dealer..... I'd question that estimate ask if there is some extraordinary challenge to working on your car. It is possible there are accessories mounted over the valve cover that will have to be moved, or that's it's a canted V-6 with one valve cover tucked up against the fire wall. Be nice, smile, ask questions.... Maybe even have someone show you what has to be moved on your engine to get at the valve cover(s). If you're going to pay that much $$$, you should learn something, also.
- 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.
