Manual Operated Lug Butterfly Valve

Q: Full Bore ball vale and Reduce bore ball valve have diferent with each other ,I want to know about them.: 1. Ball valves are generally more expensive than butterfly valves. 2. Ball valves use a face seal, butterfly valves (usually) use an edge seal. 3. Ball valves can be rated up to Class 2500 (42.5MPa), butterfly valves are rarely used above Class 150 (2MPa). 4. Ball valves can seal on two faces and can be double block and bleed for positive bubble-tight sealing, butterfly valves have a single seal and can never be assumed to be bubble-tight.

Q: I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!: For stopping leeks use teflon tape to lub your valves use plumbers grease it s good idea to have a tube around not expencive

Q: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.: I'm trying to understand what kind of shut-off this is. Most PVC valves are 1/4 turn levers, or ball joints with a T shapped handle, in both cases, when the handle is perpendicular to the pipe, it is closed/off when it is parallel with the pipe it is open/on. Other valves like a brass cock will be a round handle that you turn clock-wise to close the valve and counter clock-wise to open it. These type will turn many full revolutions. If you can't move the valve, it may be that calcium deposit has glued the inner valve into position. You might want to lightly tap it on all sides with the handle of your screwdriver as you try to turn it. Don't put to much force on it though because you will likely break it. Don't waste your time trying to unscrew the handle, that won't make a difference...

Q: Is a Head gasket the same thing as the valve cover gasket, on my honda civic si?: no a head gasket fits betweem the head an the block. the valve cover gasket goes on the cover over the valves or rocker cover are same its sits on the very top of engine

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: what is a silicone purge valve.: There are a number of things that will Toss out and ERG code on Fords (another reason I will never own another ford as long as I live) Double check all joints around the EGR valve and the tubes that connect too it. You may have a pin hole in one of the tubes or a loose coupler. If everything checks out there. Verify the vacuum line going to the EGR is not cracked, rotted, broken, or clogged. If it is replace the line. Next you need to check and make sure the valve is opening at the correct time. If the EGR is slow to open, becomes stuck half way or is opening to quickly, these will all toss out EGR codes. Then there is the possibility that the tubes for the EGR, or the EGR it's self may be clogged as well. In which case you need to remove them and clean them out. Hope this helps in your trouble shooting. Good luck.

Q: My washing machine had hot and cold water, but was leaking. I changed the inlet valve which stopped the leak, but now I have no hot water. When I put the setting on warm, the cold water runs for a bit. Then stops and no hot water comes. Any help?: I suspect the leaking valve that was replaced was your washer's solenoid valve. Did you remember to turn the hot water supply valve on after you finished? That is the valve, next to the cold water supply valve, on/at the wall behind the washer. There are rubber hoses coming from those valves to the solenoid valves on your washer. If you forgot to turn it back on after replacing the leaking valve you'll get no water. If you turn off both the hot and cold supply valves on the wall you should be able to remove the rubber hoses right where they connect to the machine and check the water flow by directing them into a bucket or pan while you open the supply vales. If you have good pressure and flow make sure there is no debris clogging the screen, just inside there the hose connects to your machine. These can get blocked where the water won't pass or runs very slow. Sometimes it pays to check the simplest causes first. Good Luck. SS.

Q: 1994 Chevy K1500 P/U 5.7 liter 350 4X4 5 speed. When the truck is under a hard pull the valves start knocking, the knock sensor adjust the timing and the check engine light comes on. The code for the light is not detecting knock sensor. I have changed the pcv valve (which was suggested) and no change. This has went on for about 5 years. Doesn't matter the grade of fuel I use. Routine maintance and tune ups have been done to this truck. The converter was taken off 7 years ago because it was clogged. The truck runs rich after the timing adjust. The light resets itself when it is turned off. ( the code is saved): hi, a common misconseption on this noise is the valves are banging or knocking, the noise ur hearing is actually caused by preigntion detonation, in other words, the fire is starting in the hole b4 it is supposed to, the plug has to be the one to start the fire, if there is excessive carbon build up on the piston and or valves it can devolop a hot spot and actually start the power stroke prematurally, what i would recommend is getting some type of induction service and injector clean, and i am not talking about running a can of stuff thru the gas tank, that stuff works but not good enough, try to find a shop in your area that sells BG products and get a induction service, if u cant find BG find something similiar, there product is very good. that truck and computer was designed to run on 87 octane, another thing that might be causing the knockin is the mass air flow sensor, i would take it to someone and have them look at it.

Q: Kenmore washer ,cold water trickles in, pressure from faucet OK. Must entire valve be replaced?: You probably can not find a rebuilt valve or get the parts to rebuild one. If needed, it will probably need to be completely replaced. There is a good chance you do not have a valve issue. Turn the water valve off and remove the cold water line at the back of the washer. Inside the hose or on the washer itself, there should be a metal screen in the line that somewhat filters the valve and protects it from getting clogged with sediment. Remove the screen and clean or replace it. If the screen wire is not at the washer end try the valve end of the cold water line. While your there you may want to clean the hot water side also. If you are unable to clean the screen, new ones are available for minimal money at hardware stores. Yes the screen wire is necessary, by removing the line additional sediment may very well go into the valve when you turn on the water and cause a valve problem if you don't have one now.

Q: How do you know if you need a new EGR valve or if you just need to clean it?: Usually it the car runs like crap at idle and beautifully any other time and you can't clean the EGR but cleaning the port in the intake sometimes helps for a check engine light with no running problems But as others said, the EGR is usually monitored with a sensor on or near the valve and the parts houses that do the free scans have a habit of convincing you the part they can sell you will fix it when usually it won't... Take it to a real mechanic shop, let them diag it for you
