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 it for? I was given a data set which is a result of antisurge valves testing every 2 seconds or so. (more than 1000 rows, measurements by time) I have no idea how to start analysis of the data like that. Can anyone help?
- I would think your spreadsheet is charting every move that the anti-surge valve makes - for example if it opens slightly, it takes a reading, if it closes, then another reading etc. Like the other guy says, it's there to basically protect the machine from surging, and no-flow. You should be able to decipher specific actions from those readings - Recycle Trip or Safety On for example. Recycle Trip is when the software sees the machine approaching the surge line and opens 10% (for example 10%), so you should be able to analyse whether you've had any of these events. As far as I know that's the only reason you would study that data - to compare the action of the anti-surge valve, with the process conditions at the time.
- Q: My house has hot water baseboard heat. In the basement, there is a wood burning stove (now it is like a radiator) that has the pipe system going through it Between the pipe in and the pipe out is a valve. Does it have to be opened or closed all the way? There is no other way to control the heat in the basement I was thinking of opening the valve half way, but I do not want to destroy the valve.
- you can definitely close the valve half way. Most gate valves or ball valves i install aren't fully open because if its completely open overtime that valve can seize up and never close again.
- Q: i have a 1970 chevy sb 350 and i need to set the valve lash what is the proper method and where do i start? everything is stock!
- I truthfully have repaired alot of Chevy engines in my time. I continually adjusted them chilly while i became into development the motor or reinstalling products....much less muss and fuss and much less oil in each single place. The GM instruction manual says ( and that i've got been doing this for years ) is with the engine in the #a million firing place ( it is set via putting your hands on the #1valve because of the fact the mark on the damper comes close to the O mark on the crankcase front conceal. If the valves are actually not shifting then the engine is in the #a million firing place. If the valves flow because of the fact the mark comes as much as the timing tab then it incredibly is in the #6 firing place, and may be became over a million extra time to attain the #a million place.) as basically desperate, right here valves may be adjusted. V8- Exhaust- a million, 3, 4, 8 V8- intake- a million, 2, 5, 7 back out the adjusting nut ( 5/8's socket ) till lash is felt ( flow or spin the push rod...in case you could flow it up or down or spin it truly..it incredibly is loose ) while play has been bumped off, turn adjusting nut in a million finished turn ( to middle lifter plunger ) Use basically slightly chalk to mark which valves you have adjusted to maintain music ...desire I helped and sorry for the long dissertation.
- Q: Also what prevents this from occuring? I have a lab due tomorrow for my biology class this is one of the questions. the answer is no where in my book, and we haven't discussed this in class. im also having a hard time finding the answer online. i would assume it would have something to do with the elasticity of the valves, and i know that when valves are weak sometimes blood can flow back into the artium when the ventricle contracts causing a heart murmur and other problems, but i haven't came across any information that talks about the valve being pushed backwards. if you can help me out that would be awesome! thanks =]
- Valves, because they open when your heart pumps and close, not allowing blood to flow backwards after the pump.
- Q: i have a 1986 Ford Mustang 3.8L V6 automatic. i need to change to valve cover gaskets but im not sure if i can do it. what do i need to do? and do i need to ad something else other than new gaskets? thanks
- Take your time when changing the gaskets. You will more than likely have to disconnect things. Make sure if you remove something it is put back. If you have to remove the spark plug wires, number them. From front to back, the left side is 1-3-5-7 and the right side front to back 2-4-6-8. I mark my wires with a sharpie but they are red wires. I use to use wooden clothes pins and write the number on the clothes pins. If you get the wires mixed up you'll have to get the firing order to get them back to the right cylinder. Good luck, you will appreciate your vehicle more now that you know the work is done right.
- Q: Our reactor is cooled by a cooling water system. The line pressure is around 4 bars and the pipe size is 42. How to select a good valve for that service?
- You'd also need to know design flow ranges, ultimate flow desired, pressure drop acceptable across valve, and the average temperature of cooling water the valve will see or the range it will see if varies much. You would need to decide if you want to use a ball valve, butterfly valve, of a globe valve to throttle the water.
- Q: The valves on our 2005 Pontiac Sunfire are bent and need fixing. Any idea of how much it might cost to have them fixed at a shop? Any estimates?
- To replace valves would probably run around $500. Plus they will probably charge you about 8-10 hours in labor to remove/reinstall the head from the block at about $90-$100 an hour. Not to mention the replacement of gaskets which could be around $100-150 So it can get pricey. I would budget for about a $1750-$2000 worst case to have this fixed. I am sure this isn't what you want to hear but once you start getting into the internals of the engine, things are going to get pricey.
- Q: and describe the direction and type of blood (oxygenated ot nonoxygenated) that flows through this valve.
- Mitral valve has two cusps. The blood flows from the lungs, where it is oxygenated, into the left atrium then through the mitral valve into the left ventricle. From here it flows through the aortic valve to the rest of the body. Two cusps, oxygenated blood.
- Q: Can I make a heat pump straight A/C ?Or some hints how to replace the reversing valve without reclaiming freon
- it depends on the unit but you can run it without the heat pump..somtimes its the solenoid and not the actual valve body that can be replaced without recharging.check the current to the valve first.
- Q: 1998 camaro3.8L v6sometimes when i start the car, it makes this loud ticking noise that goes with the RPMIm pretty sure its the valve, anyone know how to fix it, and how much it might cost?
- HI what you are hearing is not a valve but a lifter... MAYBE... Here's a couple of things that well make it tick. 1) an exhaust manifold gasket leak well sound like a ticking lifter. ( if the noise goes away after the car warms up it might be this gasket.) 2) a bent push rod well make a lifter tick ( as the tolerances would be off) 3) a bad lifter well make a ticking sound. If it is indeed a lifter then best leave it to a pro.. As the intake would have to come off to replace ALL the lifters (you can't buy just one). If its a push rod just the valve covers well have to come off.. to isolate the sound you can use a long piece of hose 3 ft. or so. hold one end to your ear and move the other around the motor compartment and see if you can tell if the sound is coming from inside the motor (lifter), inside the valve cover (push rod) or outside the motor exhaust gasket. good luck tim
