- Q: I have a 2005 Dodge Durango and had problems with stalling. I took it into the dealer with warranty on it. They said the ECG Valve is busted and its unsafe to drive. Can you guys tell me what the function of this part is?
- ECG/EKG stands for electrocardiogram. Its a way to see your heart beat pretty much. There are little waves on a screen that come up and it shows how strong or weak your heart is, and how fast or slow it beats. And what your mitral valve does is open and close to allow oxygen rich blood into your left ventrical.
- Q: My electric water heater relief valve keeps opening 30 min after turning it on.I turned it down to 90F and 30 min later overflow again.when power is off no leak with the water on uld the valve be opening because of over heating?I know it does'nt leak with cold running through it.
- the city could have put in a verify valve on the meter to maintain water out of your equipment from backing up for some unknown reason and contaminating the municipal water furnish. whilst the chilly water interior the heater receives heated from fifty 9 to one hundred twenty five levels it expands somewhat. perhaps a cupfull. without place to pass, it opens the relief valve. you would be able to ought to deploy a style tank close to your water heater. that's a metallic tank a pair of gallon in length with a bladder interior packed with air. i don't have one, yet I word a brilliant variety of properties have them now. additionally decrease the drain so which you comprehend it relatively is not plugged or leaking.
- Q: Can someone explain to me what lead and lag time are? Also, what are the three flow characteristics? Linear, equal percentage but what is the third. If I wanted to have a minimum stop at 25% on a non-linear valve such as a butterfly valve, how would I achieve this. Obviously you cannot just restrict the valve by 25% of its travel as it is not linear
- Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.
- Q: I have a 1989 Jeep Cherokee with 218,700 miles on it and my engine has thick oily gunk on it, possibly from a leaky valve cover gasket, should I change the gasket? I have been told that this is normal and not to worry about, but from the amount of this gunk, I find it hard to believe this is normal. The top of the valve cover has a light covering of gunk, but on the sides and towards the bottom of the engine. it gets very thick and at some places you can't even make out whats suppose there. Does a leaky valve cover gasket mean that there is another problem going on?Can leaving the oily gunk on the engine cause any problems?Any info would be greatly appreciated.
- Not to be mean but you can't work on what you can't see! Take the Jeep to a wand type car wash with a bag of quarters. Lift the hood and spend some time with high pressure soap and clean the entire engine and under-hood compartment. Don't bother covering anything. Leaking valve covers don't mean anything is wrong, it just makes a nasty mess. Remove valve cover/s and scrape old gasket material of the head/s and cover/s. The best valve covers in the world won't seal until the valve cover/s are completely flat. *This is an age old problem with stamped steel covers. If you want to get extra slick, chase down some aluminum cover/s. There stiffer and less apt to leak when you snug them back down. I'll let you in on a racers secret to make them seal. Buy a tube of Dow Corning or Permetex clear RTV silicone sealer. Scrape down the valve cover gasket surface till it's clean. Wipe the gasket surface down with CRC Brake Clean. Run a bead of the clear RTV on the valve cover and let it set-up for at least five minutes. Lay a Fel-Pro - Blue Stripe valve cover gasket on the valve cover. Seat it with your thumbs. Scrape-down the cylinder head where the gasket goes till it's perfectly clean. Clean the gasket seating surface on the cylinder head with C5RC Brake Clean. Lay a small bead of the RTV on the outside of the gasket which will meat the cylinder-head. Carefully set the cover on the head and gently alternately tighten them. It's OK to drive the vehicle as soon as you're done!
- Q: when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.
- SHUT OFF WATER AND REPLACE RELIEF VALVE, IF YOU HAVE HARD WATER IT CAN ACCUMULATE LIME AND FORCE VALVE TO OPEN. ALSO HEATING ELEMENT MIGHT BE BAD AND WATER HEATER IS OVER HEATING. VALVE SHOULD RANGE FROM 150 TO 210 PSI NOT 30 PSI.
- Q: what is a foot valve? how does it look? what is the application in petrochemical companies?
- A foot valve is placed at the bottom of a suction pipe, which could be used to drain a large container of liquid. The foot valve is a one-way valve (check valve) that prevents the liquid from draining back into the container.
- Q: Hi there - We have an old house with galvanized steel pipes. Our main water shut off valve leaks -- the leak is from the packing nut. A plumber came out yesterday and tightened it, and it now barely leaks at all, maybe one drip every 24-48 hours (which it probably has been doing for the 6 years we have lived here, we just didn't know when we bought the place). Rather than replacing the whole valve (which, apparently, has a high liklihood of breaking the pipes in the foundation, requiring jackhammering and whatnot), we are thinking of installing a new shut off valve higher up on the pipe, where I guess it's less likely to break. If we go for the second valve, is there a way to close up that old valve (hydraulic cement, tape, solder, etc.), so it doesn't leak at all? The tiny leak is coming from the stem of the handle - can we remove the handle and cap it off or something? (And thanks to those of you who answered my husband's question about the pipes yesterday!)

- Q: My pressure reducing valve (or restricting valve) was looked at by three master plumbers and they all said I need a new one. My water pressure has been low for weeks. It measures about 100 psi at the outside hose bibs, but it is very low inside and suddenly reduces after you turn on the facets inside. The shower is ok. My automatic sprinkler system is not able to work now due to low pressure. A relative of mine thinks we can just add a handle (as one is missing) on the valve and adjust the pressure ourselves. The repair of the valve is around $500-600! I am told in Texas that we have to have a permit and inspection to repair this valve. Also I was told by the last plumber that came out, that I have to install a expansion tank on my new hot water heater according to code. I'm not sure if that is a city code or federal. Please respond as to information you may have on this problem. The expansion tank is required I'm told when you have a pressure reducing valve for safety, is this true?
- The cost you quoted seems a bit high to me. Mine didn't cost anywhere near that amount in East Texas. A pressure reducing valve acts like a check valve when there is no flow. That is it closes as the pressure rises when you are not using any water. In this condition, the hot water heater can raise the pressure even higher since there is no place for the expanding water to go. That is the reason for the expansion tank. Without the expansion tank the pressure relief valve on the hot water heater can relieve unnecessarily or weep a bit.
- Q: I'm trying to estimate the amount of gas lost when a relief/blowoff valve is opened on a pipeline. If I know the valve opening size, pipe size, gas pressure, and the duration the valve is left open. Ex. A 12 inch pipe operating at 400 psi has a 4 inch relief valve that is open for 5 minutes. How much gas has been release? Assume constant flow of gas. Thanks in advance
- Below is one of many sites with software for sizing relief valves. Each relief valve has a specific orifice size usually indicated by a letter such as A, B, C etc. With this and the other information on the gas being relieved you can calculate the rate the valve is relieving when it is open. Note: most of the time you will be in the critical flow range so once the valve is open the flow rate will be constant until the pressure falls and the valve reseats.
- Q: I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.
