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: I am trying to replace my kitchen faucet. I have done this before, but never at this house. I can not for the life of me get the old faucet out of there. The nuts are too old and rusted, I have tried a high quality penetrating oil, that didn't seem to work. I am also not too comfortable using a torch, so that's out of the question. There was advice on another website that said just to use a good drill and drill through the nuts since I'm replacing them anyway. I'm not sure if this is really a good idea, but I am at my wits end!The other problem I'm having is I can't figure out how to get the old mounting parts off either. I can take pics with my phone if anyone needs to see them.Any help would be appreciated!!
- Go to the hardware store and buy a plumbers wrench. It's an odd looking thing that looks like it'll never work. Costs around $12.00. The hardware store can explain how it works. If you can unscrew the nuts enough to raise the fixture up but not get it off, You can take a SAW-ZALL or a hack saw blade. and cut off the rest from on top (between the fixture & the sink). Becarefull not to scratch the sink with the saw blade. try putting some duct tape where the blade may come in contact with the sink. When you put in the new fixture, coat the threads with a lithium type grease, that protects the threads from rusting and will be easier to replace next time.

- 1, may be caused by small water pressure, this situation needs to find the property to solve. 2, you can put the faucet outlet of the bubbler removed to clean up, which may have debris blocked. 3, the faucet is a control of the flow of water valve. British sinks or bathtub faucets are usually cold and heat separated at both ends. In the United States and other countries, mostly mixed faucets.

- Q: Bathroom faucet is leaking. It has only one handle on it and you turn it left or right for hot or cold. Can I switch it out, easily, for a faucet that has a separate hot and cold knobs?
- Hi, Marinewife. Sure you can. Bathroom sinks are fairly standardized for faucet mounting. Basic instructions should come with the new one. The work's all done under the sink. Tools suggested would be a "basin wrench", a "crescent" wrench, and "channel lock" pliers, plus some plumber's tape. Note that there may or may not be small chrome valves under the sink to shut off the water supplies. If not, you'll need to turn off your main water supply valve downstairs when you start the work. If you were coming to my store, you'd have what you needed and know how to do it before you left. Clearing out the cabinet and taking some pictures of what's in there, to bring with you, could also be useful. One spot - hard to see but worth a check with a flashlight - is way up in back, where the water lines are hooked up to the bottom of the faucet. If you see a bunch of rusty stuff, that could be a hard part. Everything else is pretty straight-forward. Semper Fi, Ma'am. Please come back anytime.
