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: I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?
- The proper oil at the right locations should free up the valve. Sometimes the grease from the slide accumulates in your valve, but oil will loosen it up for a short while. Some sugetions are to take out all the slides and snake and flush them with water as best you can. You should do this to your lead pipe about twice a year as well. Reoil everything and regrease the slides with a quality product. If its still gummed up ,its likely you will need to have the valves removed and professionally cleaned.
- Q: My Rodeo 96 has a P0440 code (Evaporative Emissions Control System problem). I have visually inspected the hoses on the engine; double-checked the gas cap is tight; but have not looked at the fuel tank sensors and connections. I've noticed that the EVAP canister purge valve solenoid is switching non-stop (click-click-click noise without stopping). Is it the expected behavior?
- I have seen many of the Rodeo's purge valves malfunction causing rough idle and that clicking coming from the valve. It is not normal behavior for that purge valve. Double check all hoses for any hair line cracks, they tend to crack on the bottom side alot. Otherwise replace the purge valve it make a huge differnce in the vehicles idle and performance. Also a intake cleaning service helps quite a bit too, most lube centers and shops can do it for about 50-60$. That cleans all the carbon out of your intake plenum, port runners, valves. It may help the valve to stop malfunctioning also, have seen that service clear all codes and bring back lost power and rough idles clear up.
- Q: I have an 98 Mitsubishi Eclipse rs and its a little jerky while driving and i think it might be the PCV valve but I don't know where it is located.. where is it? and would this cause the check engine light to come on?
- Your okorder okorder , which covers all Eclipse/Talon models.
- Q: Exhaust valve opening (EVO)Intake valve opening (IVO)
- HI You answered it your self... exhaust valve opening (EVO) is when the exhaust valve opens.. and the same for the intake (IVO).. When the EVO happens the motor pushes the exhaust (burnt fuel) out of the motor when the IVO happens it sucks gas into the motor to get burned and make power.. Exampe of a 4 strock motor. 1) piston goes down , sucking in air and fuel (IVO) 2) piston goes up compressing the air and fuel spark plug fires ignighting the fuel 3) piston goes down turning the crank powering the car from the explosion of Fuel. 4) piston goes back up pushing the spent fuel out. (EVO) then repeats. On a 4 cylinder car this happens 4 different times on an 8 cylinder car 8 different times and on 6 cylinder car 6 different times. When one cylender is firing another well be coming up to push out its spent fuel and another well be going down drawing in fuel and so forth.. good luck tim EDIT IVC = intake valve closes EVC= exhaust valve closes
- Q: I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink
- Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.
- Q: okay, well, I understand partials. But, on a trumpet, what does each valve do? I mean, I had this idea that each one was a half-step up from the previous...but that's not true. Is there some sort of pattern to them? Does each one have a different purpose?...Please answer as basically as possible. I don't play music very often, and I definitely don't speak brass-ish.

- Q: what are the symptoms of bad egr valve??? My car is shaking on idle.. Tune up with all has already been done.
- rough idle is one//should have ck engine lite on--get can of choke spray and fit the ext tube in it and spray around the egr to see if you can upset the idle
- Q: primary function of a valve position?
- Are you asking about a valve positioner? If so, then a positioner is a device that measures the amount a valve is open or closed and then adjusts the motive force to be sure the valve is in the position the controller calls for. These are typically use in cases of very high differential pressure or where the valve actuator may be under sized or marginal.
- Q: Anyone know what causes a heart valve to leak? I had surgery to repair mine (mitral) a few months ago, and now I have a very mild leak.
- well maybe the sugeons didnt fix it right or they cut and accedental hole... good luck in the future
- Q: The water inlet valve on my Kenmore washer leaks. Is there an easy way to replace it? Last time it broke they charged me over $100 to fix it.
- Do a Search Kenmore inlet valve. very cheap. or better yet go to Home Depot and pick one up if your warranty has run out. They will soak u for labor everytime when u can easily fix it yourself.
