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: It's filling up a 5 gallon bucket roughly ever 9-10 hours. It was leaking with an old valve and has been replaced, and after being replaced it didn't stop. The temperature has not been adjusted higher or lower, it's exactly where it was for the year before the leak started. Any ideas?: You might want to check the water pressure in your home. If it is too high, when the water is heated it expands and may exceed the pressure setting of the TP valve. You may need to lower the incoming pressure or install an expansion tank. Good Luck

Q: If I flush the toilet the drama begins. While the toilet is flushing, if I lift the lift of the lid of the tank cover NOT THE SEAT, water shoots up straight in the air from the top/cap of the fill valve. This is a picture of a toilet fill valve.: The okorder . Type in toilet fill valve in the search box and click on SEARCH. You will see a list of How-To videos that will help you with this project.

Q: I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!: Norgren okorder . You will be able to use the valve island configurator, view and download 2D and 3D CAD drawings and receive a list price for complete valve islands. The VM10 is suitable for packaging and textile machinery, electronics manufacturing and many additional applications.

Q: instead of just buying a replacement, is there an easy way off the valve to check if it's still good?: dio, yes, if your sprinkler control valve is not opening a zone valve in the automatic mode, then manually turn the solenoid on the zone valve counterclockwise, it sprinklers come on , then you have confirmed a bad solenoid. these can be purchased seperately or another oprtion is a complete zone valve dio, well, if water is flowing thru then the solenoid is not sealing on the zone valve body itslef. unless there is debris between the solenoid washer and zone valve body, then sounds like a bad solenoid...

Q: My washing machine had hot and cold water, but was leaking. I changed the inlet valve which stopped the leak, but now I have no hot water. When I put the setting on warm, the cold water runs for a bit. Then stops and no hot water comes. Any help?: I suspect the leaking valve that was replaced was your washer's solenoid valve. Did you remember to turn the hot water supply valve on after you finished? That is the valve, next to the cold water supply valve, on/at the wall behind the washer. There are rubber hoses coming from those valves to the solenoid valves on your washer. If you forgot to turn it back on after replacing the leaking valve you'll get no water. If you turn off both the hot and cold supply valves on the wall you should be able to remove the rubber hoses right where they connect to the machine and check the water flow by directing them into a bucket or pan while you open the supply vales. If you have good pressure and flow make sure there is no debris clogging the screen, just inside there the hose connects to your machine. These can get blocked where the water won't pass or runs very slow. Sometimes it pays to check the simplest causes first. Good Luck. SS.

Q: I want to wash it but don't know what to oil the valves with because I was told not to use mellophone/trumpet valve oil so would the sewing machine oil be okay to use with out damaging me Horn?I not any other safe substitutions?: If you don't get a good answer here, try reposting your question in Arts Humanities / Performing Arts - a lot of instrumentalists hang out there.

Q: Well I had a Anginogram that said I have Mitral Valve Stenosis with the LVEDP was Moderately Elevated and My Right Ventricular Moderately Elevated and My Right Atruim is Moderately Elevated what do all this mean I see my cardiologists in two weeks to go over things. Oh yes they don't say how much the Mitral Valve is narrow.: Not sure I understand the question. Stenosis just means hardening, so if your valve is stenotic, your heart is having to work harder to push the blood through the valve. This would cause your left ventricle to enlarge to compensate for the increased demand.

Q: hi i just found out i have micro valve i and have allmost 30 years with willam sydrome any doctors know more what can happen what dose walking or others got to do with the valve will i stand for a longtime walk jump will one side get weeker then the other what about my hands and eyes my knees what will happend over the years when i get older ?: I have a mitral valve prolapse. Don't know if this is what you meant or not, but it can lie dormant for a long time. I thought I was hvaing a heart attack!!

Q: hi can any one help me ajust the valves on my 1981 xs650 witch side do i start on and any help will be great i was told it is not hard i an 72 years old and i do all my own tune ups but i forget thanks pop.: Remove both spark plugs. Remove all 4 valve inspection covers. Remove the Generator cover (L crankcase cover, round, 2 screws). It doesn't matter which side you start on. Turn the crankshaft in the direction the engine runs. Depending on which cylinder you're working on, watch that intake valve. When the rocker arm pushes it down, then comes back up, the piston is then moving up on the compression stroke. Continue turning until the piston is at top dead center. You can line up the T mark on the flywheel with the pointer, or look into the spark plug hole to see when the piston is at the top. Adjust the valve clearance for the intake exhaust valves on that cylinder. Repeat for the 2nd cylinder.
