1. 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.
2.Main Features of the Butterfly Valve
(1) 90° movement for full open/close position.
(2) Excellent control characteristics.Tight shut-off even after innumerable operations.
(3) Installation cost considerably reduced because of very low weight and compact design.
(4) Longer life and reliable service with minimum component wear.
(5) Renewable seats. No supplementary gasket required with the adjacent pipework.
(6) Body & Stem totally protected from service fluid.

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:The position of the leading hole in the basin
- Look at what kind of pots and faucets you buy.
- Q:I'm having a problem with my 35154678 year old bathroom faucet.Leaking has always been a slight problem but I've always somehow been able to get it to stop if I close the faucet REALLY tightly. However, today I tried to turn the faucet shut, and the thing just popped and doesn't stop turning! It goes around and around from weak water flow to strong water flow, without the usual "resistance" before the water finally stops. So basically, I can't shut off the water flow by using the usual faucets and I have to use the main faucets underneath the sink.Gee, I sure hope I'm making sense.I guess it is time for a replacement, but can anyone tell me what might have broken to cause this? Will repairing this be as easy as simply replacing the O-rings, or do I need a plumber?
- More than likely the stop that on the stem has broken,common prob when faucet is tightened to much. You can take one out by removing the handle (usally held on by a screw somewhere,but beware you can strip out this screw pretty easy).When you get the handle off, it will usally take a pair of pliers to extract the stem(look for a big nut),after you loosen this or take it off,the stemm should pull out (again this may not be very easy,depending on the age).Take it to a hardware store and match it up. If the faucet is very old,I would probaly replace it,you can pick up a good faucet for 75.00 most places,if you do this invest in a basin wrench,it will save you hours of fun under a sink!
- Q:Home of the newly renovated toilet basin with the kind of shower that can be out of the kind of leading brand is the Hanshin but the water is very small, shower faucet and kitchen faucet out
- If it is new clothes, to see if it is blocked foreign body. Can check it out. Can be opened to open the place to take a look, such as the shower removed to the shower faucet to see if the water pipe is blocked, remove the shower after the water is not big.
- Q:How to self - study at home cappuccino
- Now Nestle coffee out of the "cappuccino that is red coffee", usually in the supermarket can buy, I bought, red factory muscle class can be straight on the trip after the snow leopard shot out there will be a layer of cappuccino foam.
- Q:I was filling a large basin with hot water. Suddenly there was a 'thump' and the water stopped running. I pushed the handle back and got cold water, then to the right and got cold water. But when I pushed the handle all the way to the left to get hot water, no water came out at all. The bathroom faucet gives hot water when I turn the handle and the bath faucet gives hot water. What happened to my kitchen faucet?
- Old water heaters get sediment, calcium deposits and other gunk. Maybe a chunk clogged the kitchen pipe?
- Q:I've read step by step tutorials I found on google, but I'm stuck at only the first few steps! After turning the water off I was going to disconnect the supply lines as well as the nut that holds the current faucet onto the sink, but it seems as if it's in the counter. I don't know if that's clear enough, but the lines run into the counter it looks like, I was wondering if there was anyway I can reach this without going to extraordinary lengths like taking the countger top off
- I think that U are describing that U cannot reach or even see the nut. there is a special wrench made called a plumbers wrench. It is a steel post about ten inches long. The top of the post has a set of horizontal jaws like those on a pipe wrench. The bottom of the post has a long rod that provides leverage so that U can turn the wrench from below. To turn the wrench in the other direction the jaws can be flipped over. Now U know why plumbers earn the big bucks ~~~~~~~ I try to not turn the water valves off in the bathroom. The valve often starts to leak and can be very difficult to change. Turning off the water from outside of the house leads to many other compllications though.
- Q:My home gas water heater, the kitchen of the faucet normal burning II OKorder Gui snapped with the Dan anchor hot water, but the shower hot water faucet no hot water, gas water heater just started running, but it is not burning, out of the cold water? The Why is this? More

For a piece of the first test II OKorder Gui Gui sneer with Dan anchor to see! Shower reasons: If the machine is no problem, then unscrew the nozzle directly from the hose to try hot water, if you can start the machine and mixed cold water is no problem, then the shower nozzle is too small water.
