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. Small in size and light in weight, easy instillation and maintenance. It can be mounted wherever needed
2. Simple and compact construction, quick 90 degrees on-off operation
3. Minimized operating torque, energy saving
4. Flow curve teeing to straight line, excellent regulation performance
5. Long service life, standing the test of tens of thousands opening/closing operations
6. Bubbles-tight sealing with no leakage under the pressure test

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. What is the working principle of manual wafer butterfly valve?
A: 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.
- Q: what is the reason for a 30 degree angle valve cut ? should i have this done on a Street performer 351 windsor with stock street heads and a mild cam?
- It will seal off better when valves close, but unless your going to increase compresion ratio with different pistons it really will not do that much good.
- Q: Okay so my boyfriend's father is getting a heart valve replacement....he's so nervous he cried last night when he heard it will be in 2 weeks....and he's usually one of those tough guys has anyone or know anyone who has had this type of surgery. They are leaning towards a animal (cow or pig) valve...because with mechanical you have to take blood thinners for the rest of your life...anyways if anyone knows information on this or knows the pro's and cons of the two diff. types of valves please give me info. Thanks
- My girlfriend just replaced her pig valve with a mechanical last year. Since I have valve problems and may face the same decision, I asked her a lot of questions. The problem with the pig valve for her was that it just started to wear out and she started having symptoms of the mitral valve prolapse with regurgitation all over again. The surgery for the replacement mechanical valve was brutal and she really doesn't like having to take anti-rejection drugs for the rest of her life. But, what she doesn't like even more is the very sound of the mechanical heart valve. It still (a year later) drives her crazy to hear it in a quiet room. It still keeps her up at night, makes it difficult to fall and stay asleep. She just cannot get used to the sound that it makes and the way it feels in her chest. I decided that knowing how this has made her feel and what she struggles with, I would opt for the pig replacement valve when I am faced with the decision.
- Q: Hey,Recently purchased a 2006 Audi A4 2.0T Q S-Line. Loving it so far but i can barley hear the blowoff valve if at all. So i am in the market for the loudest blowoff valve. I realize its a very tiny turbo but id still like to hear it and maybe even turn some heads. If anyone can help me out i would greatly appreciate it. Thank you
- The reason for this is because the car has a stock diverter valve in the car. I would not even think about putting a blow off valve inside of this type of car. This is because the car will be running to rich off of the blow off valve. This can cause a malfunction in the computer system in your car. This also will cause a check engine light which will not be able to come off unless you take out the blow off valve and replace it with a diverter valve. A diverter valve takes the air in from the turbo then recycles the air back into the turbo to give it more power. The blow off valve gets the air from the turbo and pushes it out which is why you will get the swoosh noise. There is a type of valve that will allow you to pick what you want whether you want a swoosh noise or to keep the air. You can choose the percentage and I would put in 60% divert and 40% blow off if you really want the swoosh noise.
- Q: eventually needed mitrial valve replacement or Valvuloplasty? It is also sometimes called Acquired Valve Disease, Aortic Valve Disease or Mirtral Valve Disease. Any information would be very helpful. I was not born with this condition if that helps at all.
- The aortic valves and mitral valves are 2 separate valves. The aortic is the valve that leads to the pipe supplying the body and the mitral valve supplies blood from left atrium to left ventricle. Both can become thickened, making it difficult for blood to get through. You normally will have annual or bi-annual assessment of the valve using an echo and only if it is severe or causing symptoms would surgery be considered. A valvuloplasty involves inflating a balloon to split the mitral valve - this is usually performed in patients who have previously had rheumatic fever as a child and whose valve is fused at the edges symmetrically. In exterme cases a valve replacement can be performed where a mechanical or tissue valve replaces the diseased valve.
- Q: Hey guys. I need help. Sorry this might not go here... but i couldnt find a 'good' category to put it in. This is for an engineering project for college.Im looking for shielded core solenoid valves that can with stand 95-98% sulfuric acid. With this in mind not very many materials are usable, right now we are looking for HDPE (High-density polyethylene).The size of the valves and cost is unimportant. Main thing is finding someone who sells HDPE solenoid valves.For more clarification on what we are looking for, below shows a shielded core solenoid valve from ASCO. The more acidic resistant material they offer however is a FKM. Which can only withstand ~60% sulfuric acid solutions.
- In practice, engineers do not use solenoid valves directly on chemical or process lines. They are bound to leak and cause danger particularly in your case of 98% sulphuric acid. Use a mechanical valve actuated by a motor (since cost is no issue to you) If an air supply is available, then you can use pneumatic diaphragm valve operated by a solenoid valve. Motorised valve has slower fixed open close time VS faster adjustable open close time for air operated valves.
- Q: I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?
- Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.
- Q: I'm looking for a valve that can be electronically controlled to open and close with a diameter of 1.5'(inches) to 2'(inches) and this valve must be able to withstand 20psi. Any websites or listings of stores I can go to would much appreciated. Thank you

- Q: im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- While Halo is great, Valve wins out here because of the variety of games it offers, such as the Half-Life series, Portal, and Counter-Strike!
- Q: We have a main gas valve outside and there's a gas valve by out air condition and we want to know which way if off and on .. Does anybody know !!!
- Most valves like this can be padlocked in the off position. Look at the movable part of the valve: if there's a hole for a padlock that's lined up with a stationary hole so that it can be padlocked, the gas is off.
- Q: I have several stations in my automatic lawn sprinkler system. Each station has a valve that contains: 1. Manual Shutoff, 2. Flow Control Knob, 3. Solonid, 4. Anti-Siphon valve. Any way my question is this, Why does water continue to flow even when the manual shutoff is turned off and the flow control is also turned off?
- Any manual shutoff should shut the zone down completely, a flow control will limit the volume of water that leaves the valve by resticting the valve diaphram movement. If neither is working they may not be operational. A zone that continually runs either has a plunger stuck in the solenoid, a ruptured diaphram in the valve, or debris between the diaphram and valve body. If all these are contained in the valve, the most likely cause would be a bad diaphram or debris keeping the valve from closing completely
