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:Ok I recently changed my pcv valve and today when I was checking my spark plugs I noticed and valve that looked exactly like a pcv valve on the passenger side valve cover iam not sure exactly what this valve is ?? I should note that I changed the pcv valve on the driver side because I noticed that it was just a hose coming out of a rubber grommet and into the back of the carb was that just a breather hose ? Thanks in advance for any info
- to add, support, you can simply soak pcv valve in fuel. the little eliment filter as well. pcv valve is a hard part. rattles when shaken? it's good. elliment filter is not a paper one. it too can merely be soaked. i've seen a few pcv valves that are bad. those were on engines that sat in yards for years and years. oil dried and set. had ridges that did not let the ball rattle. other than that, never seen one go bad. just need cleaning.
- Q:I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but every time I turn it on I get a different zone as they are all Zone 1 on the timer.
- This Site Might Help You. RE: I only have one irrigation valve for 6 zones? I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but...
- Q:i have a zone that - when turnd on by timer or manually only about 1 foot of spray comes out of sprinkler heads (used to wk fine). When i turn the ittle screw on top of valve (its about the size of a dime) water pressure comes up and wks fine - only water leaks at screw and when zone comes on next time NO pressure??? metal valves were just replaces about 1 yr ago.
- It's hard to say exactly what's wrong without knowing what type of valves you have since different valves have different components. In any case, I'd start by checking that the bleed screw and/or handle (depending on type) and that the flow control screw or handle (again depends on what make/model you have) to make sure they are in good condition and properly set. Be careful when turning these screws or handles don't force them past the normal stopping points. If that all checks out, there may be some dirt or debris stuck in the valve that's not allowing the diaphragm to open all the way.
- Q:For example, 2 valves from the modular 4.6 is equivalent to 1 valve from the LS1 which is a bigger valve.
- OHC generally have 2 small valves instead of 1 large valve operated by a push rod. The aim is to have the most flow possible and the least mass of valve. (avoid valve float) I cannot say anything about specifics
- Q:I am replacing my vanity sink with a Pedestal sink. I turned the shut off vales to the off position tight.I disconnected the cold water and drained the remaining water and everything was fine. I disconnected the hot and drained the water from the connecting tube but water still came out of the shut off valve at a decent pace.I placed my finger over the valve and i felt pressure build up...like when you stick your finger over a bottle of soda.I tightened the bolt on the valve and even the screw to the handle to no resolve.any ideas on how to make it stop while i connect the Pedestal sink?also, i am as novice as it gets.thanks in advance
- It's not the packing nut seal since that only seals the stem which is attached to the handle. There is an inner washer attached to that stem which shuts off the water, this is probably worn and needs replacement. Do not attempt to change this valve, leave it to a professional because it's not an easy thing to do, unless you're good at soldering. Shut off the main water supply that services the whole house. Also note: If you don't have wood behind the sheet rock from your existing vanity, you'll be in trouble, because the Pedestal must be bolted to the wall to be secure otherwise it's a safety hazard.
- Q:Would it be cheaper to get a toyota Valve body U140/240 repaired or would it be easier to swap it out... by the way the transmission valve body would cost $780
- LOL okorder DETROIT MICHIGAN! $780, my SORE LEFT FOOT!
- Q:i believe it's to do something to the valve guide to make it the right clearance n not go straight to the valve seat right? or is valve seat next?
- Once the valve guide is installed, it has to be reamed to fit the valve stem. After it has been reamed to fit the valve stem, the new valve needs to be seated in. (The valve seat should have already been done by this point) This can be done with a machine tool, or it can be ground in by hand with valve grinding compound. Once this is accomplished, the valve is removed, everything is cleaned thoroughly, and the valve is reinstalled with the spring and keeper. Normally you would do all the operations to all the valves at the same time. (That is, you don't grind in one valve, then go back and ream another valve stem. You do all the operations required at one time. So you would install all the valve guides, then ream them all, then grind or face the valve seats, then check the valve contact area, then remove all the valves, clean the head and valves up, and then reasemble into a completed head unit.)
- Q:Where is the fast idle valve located on the dx or ex model year 89-91??? I found the fast idle on my si model but its different on the base model for some reason.
- base models have no fast idle valve. if the rpm are going up and down inspect the water level in the system and have it bled. there might be air in it. if you are messing with the timing or adjusting the idle you are doing something wrong. do not adjust the throttle cable to adjust the idle. it will throw off the tps sensor. use the idle screw. if adjusting idle at the idle screw or timing don't forget to jump the ECU or you will waste your time. btw you know that the IACV needs to be unplugged when adjusting the idle right? no punn intended just checking.
- Q:I had heart surgery a little over a year ago. This surgery gave me an artificial aortic valve in replacement to my real aortic valve. Before this I smoked weed all the time, but now, I 'm on blood thinners, and I'm not sure if it's okay. Is it?
- Definitely not recommended to do any non-doctor recommended drugs while in such a state.
- Q:I'm 16 and I have a Minor Heart Valve leak, I have to take pills every time I have dental work done, and my aunt said something about maybe looking at surgery. Is it really anything to worry about? is surgery something i should really look at? and are pills really necessary?
- pass the universal care wellbeing practitioner and bypass as we communicate to a coronary heart expert who will do a coronary heart sonogram and run different attempt and for this reason might have the means to deal including your matters handy. I even have Mitral Valve Prolapse and that i in basic terms knew this with the aid of a coronary heart sonogram.
