Q: i want to know where we must use swing check valve and where we must use lift check valve in petrochemical companies. what are the differences ? are they different from the appearance? how can we distinguish between them visually?: Most swing check valves have a external plug on one or both sides of the body where there is access to the shaft. Lift checks do not have this feature. As to vertical operation of swing checks. There are many swing checks that have a restraint feature built into the body so they can operate in either the horizontal or vertical position. The main thing most people over look about check valves is the need for maintenance. The pivot pin on swing checks can wear and cause the clapper to not seat properly. In some services the internals can accumulate material and become fouled. Most lift checks have a spring that can fail and cause the valve to malfunction. This is specially true if the valve is installed in the vertical position. All checks should be periodically inspected to assure they can function properly.

Q: I have a 87 cbr600, consumes oil at a considerable rate. Took the engine out of the frame and disassembled cylinder head, block and pistons and found there is a thick layer of cooked-on oil over all sixteen valves. I figured the oil consumption was due to bad rings, but could it have been the valves?: I'm guessing the motor was running some blue smoke out the exhaust especially at start up. And I'm guessing it was probably a combination of rings and valves. She's twenty years old. Worn rings allow oil to escape into the combustion chamber from the underside of the piston and worn valve guides/seals allow oil to be burnt away from the top. When the guides/seals become worn or dry from age they allow the oil to leak down the valve stem. That's why you will notice them being worn especially at start up. While the bike sits it gives the oil a chance to pool at the edge of the valve to head surface so when the valve is first opened a accumulated amount of oil to enter the cumbustion chamber.

Q: Where is the Auxiliary Air Valve on my 98 Civic?I have a 98 Honda Civic ex and need to change the Auxiliary Air Valve: you don't have on the Civic. The Auxillary Air Valve is a part of the AIR (Air Injection Reaction) system used to control emissions on domestic vehicles. Honda doesn't use that part nor that system. there was another 'auxillary air valve' used in old Bosch fuel injection systems that added air when the car was in cold start enrichment. that part hasn't been used in the last 20 years by any manufacturer. The control of the idle at cold start is done by the idle air control valve. The idle air control valve located under the thottle body on most hondas; some models have it on the side. there are usually two vacuum hoses and one electrical connector to the valve. that valve controls the engine idle and when bad it would cause the engine to surge at idle. if that's not the case, then we need more information on what you are trying to fix and what you mean by auxillary air valve. if there is a diagnostic trouble code associated with it then that would help. hope that helps

Q: hi My Dad is 65 yrs old. he is very fit and healthy. He has had heart problems as long as i remmember! he has been under care for almost 2 years now and he has had to stents put in. Now the doctor has found out that his Mitral valve is leaking. They have told him tat he needs surgery to either have the valve replaced or repaired. i like to know if anyone out there has been through this and can help ease this a little as Ia really worried!! Thank you!: Mitral valve surgery is surgery to either repair or replace the mitral valve in your heart. Minimally invasive mitral valve surgery is done through much smaller incisions (cuts). In open surgery, the surgeon makes a large incision (cut) in your breastbone to reach the heart. Mechanical heart valves do not fail often. However, blood clots develop on them. If a blood clot forms, you may have a stroke. Bleeding can occur, but this is rare. Biological valves tend to fail over time. But they have a lower risk of blood clots.

Q: I just installed three anti-siphon valves(jar top,orbit) for a sprinkler system the main water line is 3/4 then goes into my manifold (pvc)3/4 schedule 40,usually when you turn on the water it comes to a stop where you re valves begin then you either open them manually or their set up through you re timer, the problem im having when i open the main water line the water goes straight through the valves without me even opening them my question is can it be to much pressure or what can the problem be? any info helps thank you: possibly they can give some insight on your problem.

Q: Or is our money stinky? is the $59 we paid not equivalent to that paid by xbox360 ps3? Please help!! I am sick of getting killed every 5 minutes. Is VAC false advertising?: Valve?! Valve has nothing to do with COD MW2. Valve makes much BETTER games.

Q: recently changed head gasket. could valves tap from the push rods being mixed up? they all seemed to be the same size and i know the other side was exactly the same when put back together but this side is mixed up. could this make the valves go crazy? and i need to replace my water pump because its getting very hot and no coolant moving. and everything is smokin up, took off oil cap and it was steaming. would that have anything to do with making the valves tap?: there okorder a good site that will help you fix your car and its free and you can ask master tech for help.

Q: A friend of mine is having open-heart surgery next week to replace a heart valve. He needs to decide whether he wants a mechanical valve or a biological one. He is 28 years old. Which would you choose and why?: The answer depends on many things. Which valve? Why is it being replaced? Overall, mechanical valves last longer, typically 20-30 years. The tissue valves tend to last 15-20. There are risks and benefits to each, such as closure efficiency, infection rates, and other types of failure etc. If it were me, I'd go with a mechanical valve. However, he really, really needs to talk seriously with his doc before deciding. The doc will give answers in context to his unique situation. That is something we cannot do on this site, simply because we do not know him or his medical history. Best of luck.

Q: hi ihave a 2001 1.4 civic (6th gen) has anyone got any info/reviews on the following mods: powerboost valve, denso/splitfire spark plugs(which one would be better) and splitfire ignition leads.: While I'm not familiar with the power boost valve specifically, it looks similar to a rising rate fuel regulator which is used more for forced induction applications like turbocharging and supercharging. If you were to install this on a relatively stock car you would risk running an extremely rich mixture that the stock ecu would be unable to compensate for which in turn could cause damage to your engine. The stock fuel regulator that currently sits in your car is more then sufficient enough to keep up with simple bolt on parts and shouldn't need replacement unless you are planning on doing true engine work or forced induction. As far as comparing different companies' spark plugs and wires it would really be a matter of splitting hairs.
