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. 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.
2.Main Features of the Manual Wafer Butterfly Valve
1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
6. Long service life, standing the test of tens of thousands opening/closing operations
7. Bubbles-tight sealing with no leakage under the pressure test

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: I accidentally pushed the pressure release valve on my hot water heater last night. It ran for a while, and did not stop. I turned the water off, the valve on the cold water piper above the water heater, and it stopped running. Will this stop running at some point? The overflow tray fills too quickly for me to drain it. When I turn the water back on it starts pouring out again. HELP!!!
- After long periods of inactivity, mineral deposits will form on the pressure side of the valve. When you pushed the valve some of the deposits likely lodged in the valve preventing it from closing all of the way. The good news is that you need not replace your water heater. The bad news is you will likely need a new valve. It is important to replace the valve in these situations because the same mineral deposits that prevent it from closing now can also prevent it from opening when it is needed to relieve excess pressure.
- Q: I have a 1987 Chevy Blazer with a 5.7 liter 350 engine. Where is the PCV valve located on it?
- You will find it in a valve cover, PCV valves have been put there for years and years now, and this is usually the first place you should look. If you cant find it then you may need to start googling this one!
- Q: im having trouble locating the pcv valve on my 1979 oldsmobile. i have a 305 engine. i need to replace it asap, so any help would be appreciated. thanks in advance to all feedback.
- Facing the engine, should be on your left valve cover. Has a hose attached to it and sticks into the valve cover.
- Q: what do the doctors do and is it dangerouse? aslo how do you get a cloged valve?
- they are dangerous and you get them sometimes form cholesterol and stuff, the doctors clean it out sometimes unless you are in real danger when you have it removed
- Q: we are researching fluid power (pneumatics and hydraulics) in my high school engineering class. Does anyone know another name for a valve? I've been able to find different types, but I can't come up with any different names for a valve. Anyone have any ideas?
- Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.
- Q: How do you know if you need a new EGR valve or if you just need to clean it?
- Take the car to a dealership (Ford, if you have a ford, etc.) This could save you being ripped off by a shade tree operation. Believe it or not, lol, there are some crooks out there!
- Q: i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank
- srry but if u do that it works very poorly so i would buy that scuba tank
- Q: As title.What's an easy way to remember: mitral valve leaflets are anterior and posterior leaflets; tricuspid leaflets are anterior, posterior, and septal (medial); aortic valve leaflets are left, right, posterior leaflets; pulmonary valve leaflets are left, right, anterior leaflets?It's easy to remember all but one valve (mitral) have three leaflets each. Physically aortic root sits behind pulmonary trunk, I guess that makes it easy to remember aortic valve has left, right, Posterior; and that pulmonary valve has left, right, anterior leaflets. Where I'm running out of ideas now is how to remember tricuspid has anterior, posterior and septal leaflets... Please help.Thanks.
- The tricuspid valve has three leaflets which are thin and membranous with commissures that appear more like indentations than true commissures. The TV apparatus is similar to the mitral valve but has greater variability and thinner leaflets. The three leaflets are the anterior, septal and posterior leaflets, with the anterior and septal being larger than the posterior leaflet. TV= tricuspid valve tri-cuspid=3(three leaflets) leaflets=3leaflets Tricuspid: Having three flaps or cusps. The valve that is called the tricuspid valve is situated between the right atrium and right ventricle and permits blood to flow only from the atrium into the ventricle. The aortic valve in the heart also has three cusps. Tricuspid valve (Anat.), the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; -- sometimes called the tricuspid valves, each flap being regarded as a valve. Take care as always
- Q: What is the primary function of valve seals?
- A 'leak-down' test is the best bet, indicates the place in the process the compression is leaking and if it's across the valve stems than for definite the seals need replacing. Are not able to judge it via the smoke correctly as oil would be slipping previous the rings also.
- Q: Half-Life 1 and 2 to me were masterpieces. It would be a shame if Valve ended the series there.Is Valve going to make Half-Life 3 in the near future ? If so, do you have any proof ?
- Valve is currently working on the next iteration of the Source engine, and when they finally finish development of that, then I think we can start seeing a newer generation of games from Valve that hopefully includes HL3.
