- Q:what's the function of a car valve???????????
- Cylinder head valves come in many designs and combinations. Their may be two, three or four valves in the head and combustion chamber that open and to let air and fuel in while the piston compresses the mixture and is ignited near top dead center. When the piston is near bottom dead center the exhaust valves open where the piston pushes the spent gasses out underneath the open exhaust valve. As the piston nears the top of the exhaust stroke, the intake valve opens to allow the air/fuel to enter the combustion chamber and cylinder bore. As the piston sweeps down vacuum is created in the cylinder and more fuel / air enters. When the piston reaches the bottom of the intake stroke, the intake valve closes in preparation for the compression stroke. Go to the Wikipedia Encyclopedia ot How Stuff Works to see how a four stroke engine operates. You'll see what the valves look like and how they work.
- Q:So outside we have a gas grill. There is a valve to turn when you want to use it. U can only hear the gas going when u turn the burner knobs but say u left the valve open and no knobs turned at all for 5 hours is gas escaping or does it only escape when the grills knobs are turned? Thanks
- The valves on the grill itself are the ones that allow the gas to flow. As long as you have no leaks between the main valve and the grill valves, no gas will flow when the valves on the grill are turned to the off position.
- Q:We have an oil steam system. There are Dole valves - 1A on each of the radiators. We bought new ones. They don't seem to be working. They look like a bullet shape with a screw in (on the side of the bullet) to the radiator. On the top of the bullet is a slit with numbers 1-10 on a dial. A picture we saw on the web showed a plastic piece of tubing in the screw part which looks like it goes into the radiator. If we remove the valve, the radiator gets hot with steam coming out of the hole. With the new valve on, the radiator barely gets warm. We're in Piscataway, NJ 08854. H-E-L-P.
- First off these are vents , the valves are at the bottom of the radiator where the pipes come in. Sounds like the vents are either closed or broken. Try turning the adjustment screw if that doesn't work I recomend replacing the with vent from a company called ventrite the valve you are looking for is a vent rite #1. These are adjustable vents used to balance the heat throughout your unit the dial at the bottom is labeled 1-8 start with all of them on 8. Now when the radiators heat up if you find some are getting hotter faster turn those down a notch and check again in a day or so.
- Q:How do I know if the valve seals need replacing? From what type of smoke can I detect?
- A leak down test won't tell you anything about the valve stem seal. It will about the actual valve face sealing in the valve seat, but the valve is closed when performing a leak down test. The best way to diagnose worn valve stem seals is if you get a lot of oil smoke onstart up, but it goes away in a few minutes. A real giveaway on bikes is after the bike has set on the side stand overnight and when you fire it up, you get more oil smoke out of the left side muffler than on the right side muffler. That's because the oil in the valve area runs to the left side when parked on the side stand.
- Q:I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???
- I've never seen an EGR valve failure on these engines. It's almost always the vacuum solenoid for the valve that has failed. I've also seen issues with vacuum lines breaking or becoming plugged but that's pretty rare. It's just a shame that so many shops have parts throwers nowadays, get a code for the EGR valve and instead of taking 2 minutes to use a vacuum pump to test the valve, they just replace it, and then not even bother to drive the vehicle before giving it back to confirm their repair... terrible! They are giving the people who try a bad name.
- Q:From searching around I feel that I need to replace this on my vehicle. Is the Suction Control Valve different from the Idle Control Valve? Sometimes at a stop light the engine will stall. A couple times it has happened while driving when coasting to a turn or stop.
- I would think the suction control valve is what is also called a purge valve and is part of the emissions control circuit. It is not the same as an idle control valve nor will it cause poor running when it fails. The idle control valve will however..
- Q:What is the International Standard or other acceptable calculation or table for determine the air supply of pneumatic actuator in shutdown valve 6 to 24.Desired answer will be air flow in SCFM.Thank you.
- Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).
- Q:Electric Hot Water Tank Pressure Release Valve Leaking, Why?
- They build up mineral deposits on the valve seat sometimes that will cause them to leak.Try lifting the lever to open it completely then flip it closed. That will sometimes clean the seat and stop the leaking. It might take two or three tries. If that doesn't stop the leak then you'll need to replace the valve.
- Q:How do you take out a valve stem?
- no, the cap for the valve stem is designed to keep dirt out not hold air in ! there is a special tool that removes the valve stem, and some manufacturers have cleverly placed it on the top of the stem cap(so you would remove the cap ,turn it upside down and the metal tool will fit into the valve and unscrew the stem.), otherwise you can get one at the tire dealer or SEARS ,It's about the size of a pencil
- Q:Is there a product that can fit over a foot valve to give it further protection in muddy water? I am looking for something for forest firefighting in mind. Something like a screen box something else that can give it further protection. It would be nice if it was small, and compact. Pictures would definitely be an asset. Thanks to everyone that answers. Greatly appreciated.
- most foot valves i have bought come with a strainer attached perhaps you should look for that type. if your valve has a strainer you may consider making a further coarse strainer out of a ball of chicken wire and place this over the foot valve assembly(thats what i do for the cold water supply to my house) don't compress the chicken wire very small as it will block up i tie the wire filter on with galvanized wire then i can easily replace it if necessary ps i tried stainless steel pot scourers but they were to fine and blocked easily
