Manual Operated Lug Butterfly Valve

Q: wut is the purpose of this valve on tanks and on piping? explain wut the vacuum part does and wut pressure does? thanks: The pressure relief valve is to protect a tank or piping from rupturing from excess pressure. A vacuum relief valve would prevent tanks and piping from collapsing from too little internal pressure.

Q: I know absolutely nothing about cars. My AC stopped working, I had a new air compressor, drier, expansion valve put on. It was also vacuumed out. Problem is it will not take a recharge, and there is no refrigerant in it at all. But it keeps reading high pressure, I don't know the readings I was told it is reading high, and will not take a recharge. Someone on yahoo answers suggested it might be the Schrader valve is this a problem that it can cause if it's bad that it will not let you recharge, and read a high pressure reading? Is there a Schrader valve for the low pressure valve amp; the high pressure valve or is there just one? I have a 96 Dodge Stratus ES. Thank you for any help or ideas.: 2 valve 1 low 1 high the valve is cheap (looks like the same as one that goes in a bicycle innertube) but if a shop puts it the labor price for your area, here around 75.00 this dont make sense. to have high pressure there has to be something in the lines. and the valve would be open to give you a reading so unless its leaking its working. with a vac on it and 0 134a you should have a reading of -20(+or-) in of mercury on the low side (below 0) and 0 on the high side. If the high side valve was not depressed (opened) then you would have the can pressure reading (about 80psi depend on temp) only if you tried to fill from the high side. Ok try this find the line going to the firewall and inside the car, this is the low (return) line. dont use the one that goes to condenser at the front of the car (the radiator looking one). find the fill valve and thread on the fitting (may have a cap on it) tighten the fitting until it is tight then use a pair of pliers and turn 1/8-1/4 turn more then try to fill.

Q: I have a mountain bike that my brothers left me. the tire in the front is a normal s valve, the one in the back is a presta valve. now this was ok because it was fully pumped up, but then it popped on the road, so i got a new tire ad put it on and was all ready to pump it up but when i tried to pump it no air would go in. so i looked at it a while and i figured out the top unscrews, so i unscrewed it and put the pump back on and started pumping, but after a while i figured out that no air was going in the tire and now i'm very confused.: no longer understanding the make of motor vehicle i won't be able to be particular. A valve cover is a straightforward bolt on area. maximum engines won't require an outstanding form of different areas to be bumped off yet that may no longer consistently the case. purely get rid of the bolts/screws protecting the valve cover on and carry it off.

Q: I'm installing an under-sink water filter. For the saddle valve, how do I drill the 1/8 hole through the iron pipe? What is the easy way to do this? Seems like I will be slipping around a bit. Any tips on this step?: My under sink filter hooked up the the cold water supply valve with compression nuts. There was no need to use a saddle valve. You could consider getting another type filter or follow mrrosema's instructions.

Q: This happens when the sprinklers are ON and goes on for a minute after the sprinklers go off. Should I replace the whole valve or do I need to check the diaphram or solenoid head? In addition to leaking, I have noticed a more potential problem - water hammer. As soon as the sprinkler goes off, I hear this loud banging noise from the pipes underground. Water pressure is fine ~ 50. My guess is air inside the pipes is causing this. Is this because of faulty valve which is leaking?Also, any difference between the valves that are sold in Lowe's and Home Depot to that of commercial valve? My lawn guy says commercial valves last a long time.: The water hammer is due to the sudden closure of the control valve. They don't turn off slowly. The sudden shutoff of the valve causes the inertia of the water to slam against the end of the sprinkler pipe. You can device from a well stocked hardware store to place in you water line to reduce or eliminate the hammer. As for the leaking problem, I disassembled the control valve and found the diaphragm out of position. On mine, there is a very, very small key on the diaphragm that aligns it with the case. Also check for debris in the solenoid valve seat and anywhere else in the valve. I can't address commercial vs residential valves other than if the valves are brass, they are more durable.

Q: Does a diverter valve even make a sound at all?: I have had both on my car. A blow off valve gives off a loud Hiss. If you want to know what a diverter valve sounds like when it vents, flick a metal pipe with your finger. Its kind of a metallic clink noise that is much quieter then the blow off valve. BOV's are also illegal in many places as it is venting exhaust gases to the atmosphere. BOV's are also much more likely to cause your Check engine light to come on because the mass air flow sensor has an idea of how much air should be passing by it. When you put a blow off valve in, that air pressure is vented to the atmosphere and the mass air flow can give false readings causing your fuel mixture to be changed. The diverter valve does not vent it to the atmosphere but sends it back through the intake system again so your CEL shouldnt come back on

Q: I am trying to shut off the water valves under my sink to install a new kitchen faucet. The hand knobs appear to be damaged (thin soft metal). In addition, they seem to be seized up pretty well. So I can't shut them off by hand and not sure what I can use to close it off without damaging it further. My initial thought is to replace the valves. Any suggestions?: This is a common problem. Don't force/twist them or they could break off. You will need to shut of water to your house [assume it is a single family?] The shut off is frequently in the front of the house where the water enters and could be under a hose bib [outlet]. Don't confuse the water shut off handle with the water pressure regulator, a dome shaped metal cylinder attached to the incoming water pipe. If you can't find the shut off there is usually one on the water utility's side of the water meter - closest to the street or road and sometimes one just on the outlet side of the water meter that you can twist by hand. After shutting of the main water supply to the house relieve pressure at a low point - usually a hose outlet. This way when you remove the water supply valve under the sink you won't get a cascade of water. You may want to douse the shut off [sometimes called angle stops] with some penetrant like PB Blaster penetrant and let it sit. You may want to purchase 1/4 turn ball style shut off valves as opposed to the twist or gate style. Note the size inlet, IPS 1/2 inch, 3/4 etc. and the outlet size, generally 3/8' for new faucets. Take a photo with your phone or a digital camera and take it to the store when you purchase new shut off valves. If you have a dishwasher and the water supply goes to the hot valve, then be certain to get a shut off valve with two outlets and use it on the hot side. If you are in a condo or multi-family you will need their permission to shut off the water unless each unit has it's own shut off [more typical of town house style than apt style condos.]

Q: My husband went to the doctor today, then called to say he won't be coming home because he has infective endocarditis. They sent him to another, larger, hospital in the region. Hours later he called and said that he needs surgery on the valve and they are moving him to another part of the country. I've been trying to read about it but I'm not sure I understand. What I've read says that they have to treat the infection with penicillin first, the he can have surgery. However, he's telling me he might have surgery when he get to the other hospital. He needs a new valve. Does this mean that his condition is worse than those I've read about or that they are simply doing things differently? Also, if you know. Does other illnesses make the risks much higher? He's got aspergillus in his lungs and have had 2/3 of the lungs removed. He has an immune deficiency (HIES) and he is physically weak from being sick. I know it's not good, but how bad is it?: Infectious endocarditis. Of course, any endocarditis is an infection. Rather like saying an 'infectious cold.' You will need to discuss this with his doctor to get good information. That means you go where he is. If you need to you make an appointment with the doctor at his office to find out. No way to know what kind of heart value issue he has or what other kind of heart condition he has.

Q: Does anybody know what the valve lash specs are on a 1986 chevy sprint 1.0L carbureted?: if you cant see clearly, just right click it and choose save as so you can enlarge it. this will be important. now... Rear of vehicle side = Intake valves Font of vehicle = exhaust valves Rotate crankshaft clockwise and align the timing notch on the pu;;ey to 0 on the timing tab. Remove the distributor cap and ensure the rotor is at 3 oclock This position indicates the is at compression stroke. TDC #1 cylinder. Using feeler gauge between rocker and valve syem, check intake and exhaust valve clearance on cylinder #1. After adjustment tighten the locknut to 11 to 13 ft pounds torque.

Q: First off I'm a girl. :) My 2.0 non turbo engine has a bent valve. I have been asked to pick up the valve. But I need to know if its for the intake or the exhaust. I know the guy how is going to fix it said he will have to sand down the cylender that it goes in it. The car sounds like it knocking when driving or sitting still. The guy who is going to fix it is at work right now and I'm suppose to order this part right now. Is it an intake or an exhaust valve?: tell him that you dont sand down the seat.if he does,then he could get it so it wont seat right.he needs to lap the seat.now 1 of the valves are smaller then the other.if it backfires through the exhaust then its the exhaust valve.if he know how to do it,then all he has to do is take a piece of paper and hold it up to the tailpipe and see if it sucks the paper in.
