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. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

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.

 

3. What is the working principle of manual wafer butterfly valve?

 A: 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:Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??
Well, generally it's going to be .030 intake and exhaust (hot). Adjust to those clearances cold then recheck at operating temp. But it would really help to know year, make, cu. in., which aftermarket heads, to be absolutely sure. On some engines it is .024 intake / .030 exhaust and so on, depends on the lifters and valve train geometry.. What brand of lifters and cam profile? Usually they will specify valve lash and adjusting procedures. Edit: Wow, kinda' tight valve lash, krazybob, ( might be a lttle tough on the old cam lobes), and then there is your timing numbers / advice with absolutely no details to base it on ( H.E.I.?..which brand? / mechanical advance curve?, and vacuum advance numbers?, cam timing, brand of lifters, cam specs, rocker arm ratio)...Look, S-51D, the best idea is to Do- It- Right using the correct adjustment specs. The data is out there, once the configuration is identified.
Q:How many kinds of butterfly valves are there?
1. according to the structure classification (1) Central sealing butterfly valve (2) single eccentric sealed butterfly valve (3) double eccentric sealed butterfly valve (4) three eccentric sealed butterfly valve2., according to the sealing material classification (1) soft sealing butterfly valve. (2) metal hard sealing butterfly valve.3. according to the form of sealing classification (1) forced sealing butterfly valve (2) pressure sealed butterfly valve.4. classification according to working pressure (1) vacuum butterfly valve. 2) low pressure butterfly valve. (3) medium pressure butterfly valve. (4) high pressure butterfly valve. (5) ultra high pressure butterfly valve.5. classification by working temperature (1) high temperature butterfly valve. (2) medium temperature butterfly valve. (3) normal temperature butterfly valve. (4) low temperature butterfly valve. (5) ultra low temperature butterfly valve.
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:What is the difference between the installation and function of a butterfly valve and butterfly valve?
Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
Q:Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?

Q:When i waa replacing the valves in the las 4 valves , they dropped and i dont know how to make them go back up, and i dont want to take the engine out of the car, is there any tool to make the valve go back up or there is any way to do it?? People told me that i can crank it by and , but i dont know how to do it where do i have to do it, i need help please im begging for help!
You could use a socket and breaker bar on the bolt on the end of the crankshaft to slowly and carefully rotate the engine by hand. But if the valve is all the way down into the cylinder, the only fix is to remove the cylinder head. If you have been asking for days, maybe, just maybe, you are in over your head. Bring the car to a reputable mechanic and pay to have it repaired. Repeating the same question obviously isn't helping at all. All you are accomplishing is to irritate the people here on Yahoo Answers.
Q:Specifically an engine valve retainer.
TRhe retainer and locks works together to hold valve to spring and keep valve from falling into the cylinder and spring from coming off the top. The locks are tappered, small end at bottom, big end at top. You compress the spring down, drop retainer over valve, put locks in groove of valve stem and pull up on the retainer to lock the retainer and locks in place, the relese the pressure off your spring compressor and the valve spring now holds pressure up on retainer which forces up on the big end of locks and holds everything together
Q:Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
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.
Well a lot of valves signify that more air/gas is getting to the engine so it suggests a more powerful engine. So your car has 4 valves per cylinder. Now that's pretty much a standard number so most expensive cars don't really even talk about that. They mostly just advertise the displacement. You can't really tell the type of engine via the number of valves because it does vary by manufacturer. For example there could be a 16 valve V8 also also(2 valves per cylinder). There are some ratios that dont work like a 16 valve V6 because you cannot have 2.6 valves.
Q:Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!
An import shop can probably do this in two hours and cost should be in the general range of $200-300 I'd estimate. There is a camshaft that acts on the valves, and there is a predetermined amount of play or slop in the system that is within specs. As the valve seat wears, the valve gets pulled further into the head, and this lessens the play as it wears. If it gets too tight and fails to have any play, the valve won't be held tight against the seal and it will leak, lose power and possibly burn the valve. So yea, get it set. Also may want to factor in timing belt cost and ask about that and water pump as those aer replaced together.
