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: Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
- Firstly both conditions are not necessarily serious. Prolapse is the phenomenon of one or both mitral leafets bending slightly into the left atrium when the heart contracts. Normally when the leaflets close they dont clise straight but form a slight tent shape facing towards the LV. With prolapse the leaflet bends beyond the imaginary straight line of the valve annulus. Regurgitation is simply back flow through a valve when closed - all valves function as one way check valves to ensure one way flow through the heart. Its completely normal to have a small amouny of regurgitation at all valves except the aortic valve. Mitral regurgitation typically worsens with prolapse because the valve isnt closing properly. Usually prolapse and mitral regurgitation are not all that serious and only require periodic monitoring. Consult your DR if you suddenly develoop symptoms like chest pain or breathlessness. These can indicate the valve is degenerating further and may require medical treatment.
- Q: when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.
- SHUT OFF WATER AND REPLACE RELIEF VALVE, IF YOU HAVE HARD WATER IT CAN ACCUMULATE LIME AND FORCE VALVE TO OPEN. ALSO HEATING ELEMENT MIGHT BE BAD AND WATER HEATER IS OVER HEATING. VALVE SHOULD RANGE FROM 150 TO 210 PSI NOT 30 PSI.
- Q: Hi, I just got my 20 gallon freshwater aquarium yesterday and set it up today with the filter,water, pump,etc... I bought an AquaCulture 20-60 gallon double outlet air pump and didnt realize it had two valves. I only need to use one though ...what should I do??p.s. The bubbler thing that lets the bubbles out is a rectangle and its long but it isnt working in the middle of it...? would that be because of the double valve?p.p.s. the pump came with two check valves.Thanks, Sarah
- If the pump doesn't come with any method to shut off one of the outlets, you can combine both outlets into one by using some tubing and a T-valve. You can also use an air valve and some tubing on the unneeded outlet to dead-end it, though that method may be a bit more stressful on the pump.
- Q: I am trying to shut off the water valves under my sink to install a new kitchen faucet. The hand knobs appear to be damaged (thin soft metal). In addition, they seem to be seized up pretty well. So I can't shut them off by hand and not sure what I can use to close it off without damaging it further. My initial thought is to replace the valves. Any suggestions?
- You don't have to go through all that crap. Get a can of PB Blaster or Deep Creep. (penetrating oils) Both oils far away better than WD-40. Spray the stem of the valves and wait,..... about 20 minutes. if they are still stiff, apply again, wait another 20. Then if its not fine and ready to go, THEN go through the hassle...
- Q: I want to install a hks blow off valve on my car but is it true that i need a turbo installed first in my car or not.and are they legal in the state of californiapermitted,i want my car to make that air release sound when i shift gears,but it needs a turbo installed or can i still get what i want from a blow off valve without a turbo!!!!!
- Get a turbo car and then install the bov.

- Q: how do you replace the pcv valve on a 1997 ford escort
- VERY easily. The rubber hose that is routed to the top of the throttle body on one end, is connected to the PCV valve on the other end, where the exhaust manifold is situated, by the radiator cooling fan.
- Q: i dont get how valves produce the sound? and why did we change to solid state? was that because they we're used in stereos?
- Most valve amps I have used reproduce the sound of a tube amp. Tubes have a warm sound and can be overdriven to get that good rock crunch distortion sound. We went to solid state because they were durable and didn't require the maintenance of a tube amp. Printed circuits and transistors cut the cost of manufacturing. The old tube amps still have the purpose and they never quite matched the exact sound of tubes with the solid state amps. That is why they are making a lot of tube amps now.
- Q: Would a 96 saturn egr valve work on a 96 camaro
- A EGR valve is a simple ball/check valve. The only two connections are the hose from the intake manifold and the grommet the valve pushes into in the valve cover. If it fits, it fits. They're only a couple of bucks, so you'll waste more time monkeying with it then just buying the correct one.
- Q: Hey Guy! So I Was Thinking About Buying A 93 Honda Del Sol For $1800, But The Guy State That It Need A Valve Job Now Im Not To Sure What Is A Valve Job Is And How Much It Would Cost... So Please Help Me Out... I Really Need A Car :-/If Needed I Live In South Of California
- Nissan skylines are the two 4 cylinder or 6 and clearly this one is a 6... properly it somewhat is no longer the perfect description...if valves are worn or sticking you could lose compression. Compression is while the piston compresses the air/gasoline mixture and if the cylinder has a leak someplace then you somewhat finally finally end up dropping some potential and gasoline performance. Doesnt propose the top of the international - a mechanic will could desire to do a compression attempt to confim and there is an possibility they'll could desire to eliminate the pinnacle (genuine element of motor housing the camshaft and valvetrain) to evaluate what's inflicting the compression loss. perchance a valve spring or lifter is worn. with a bit of luck it won't value too plenty.
