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.
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. Bubbles-tight sealing with no leakage under the pressure test
7. Wide selection of materials, applicable to various mediums

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:im trying to turn on my sprinklers from the valve manually,but doesn't seem to work, the valve it's an antisiphon rainbird valve with two little knobs, I know that one is the bleeder and the other the pressure control, or something like that, and the solenoid has the on and off arrows on it, but i can't do it anyways,they come on automatically right on time ,it's just the manual thing that i can't do, please help me,i really need it

- Q:1991 Buick Spirit smokes early for five minutes in morning, from exhaust. Tried every carburator and gas cleanative fluid. Mechanic says Valve job'.
- Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.
- Q:When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!
- The flow coefficient is a measurement usually given for a valve fully open, identified in the specs as the Cv. It basically tells you how much flow you'll get through the valve for a given pressure differential across it, or conversely how much your pressure will drop if you force a certain volume through it. Some valve types are effectively orifices (gate valves) or short lengths of pipe (non-full-port ball valves), others like solenoid types have more complicated internal paths the reduce flow because of the fluid having to change directions in addition to squeezing through orifices.
- Q:If I buy one of those Presta valve adapters can I just screw it on and leave it on while I ride? Will I lose air pressure at to fast of a rate?

- Q:My valve covers are leaking how do I take the intake off my v6 firebird?
- You probably don't need to. Just tighten the screws up a little bit. several years, GM decided to use gorilla snot (silicone) instead of real gasket material. THis was a BIG mistake. I don't know if this is what you have. If this is so, Fel-Pro makes wonderful REAL gaskets. IF you need more info, check with local libraries for the ALLDATA data base. It shows you everything in great detail. Sometimes, oil gets forced through covers due to a clog in the oil pressure relief valve, which is part of your oil pump. You should do a chemicla engine de-sludge to clean this thing out as a preventative to futire woes. THen switch to a good synthetic oil, like Mobil One or Pennzoil Platinum. Your engine will just LOVE you for it!!!
- Q:what the valves adjustment spies in the 1979 Mercury-marine engine, 6 cylinder in-line 165hp 4.089L?
- There are 2 different ways, with the engine warm remove the valve cover start the engine and 1 at a time back the adjuster nut off till the lifter starts to click and tighten it 3/4 of a turn going 1/4 turn at a time this is very mussy with oil all over everything. The easiest way is to turn the engine to number 1 TDC and back off the adjusters till you can just turn the push rods with your fingers and then retighten 3/4 turn do this in the following order #1 E+ IN #2 - IN #3 E #4 - IN #5 - E--- then turn the engine 1 turn to number 6 TDC and adjust the remaining valves the same as the first in this order # 2 - E # 3 - IN #4 - E #5 - IN # 6 IN+ E Then reinstall the valve cover and your done much cleaner way
- Q:Does the new valve get glued or anything or do I just put it on tightly? I cannot tell if the existing valve is glued on or not.
- Is the new valve or the old valve the compression type? If the old valve is then as you take it off you will discover if it is glued (I doubt a compression valve is also glued). Replace the old valve with the same type as the old one. That is always a good rule of thumb to follow. Put it on tightly but DO NOT over-tighten it. 1/4 turn past tight it usually tight enough. I am not a big fan of compression fittings in either copper or cpvc. You may wish to put a glued valve on, if you already have the cleaner, the primer, and the glue, other wise the expense of the materials does not warrant their purchase for the changing of one valve.
