Q: I was just wondering if any body got there valve replaced,and if they are still having symptoms..Such as sweating,and shortness of breath.I do not know if i should see a cardologist, or the surgeon who replaced the valve.Any answers would be appreciated.Thank you.: Any side effects directly after or shortly after a major heart surgery or valve replacement would best be followed up by a visit to the cardiologist to make sure there are no other problems or problems with the new valve. This is a serious question and should be treated as so. Go see a doctor asap. That way, if nothing is wrong you have a piece of a mind instead of waiting and waiting.

Q: And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :): a vale job is nothing it means nothing you dont get a valve job you get new heads... are rarely do they cause actual not functioning of the car. you have an old car that has seen better days. and age is catching up to it. the car itself is not the best made car and at best im surprised it hasnt hit the junk pile yet.

Q: looking to get a greddy type rs blwout valve for my sti, but i wana noe wut exactly da blowut valve does....kause i just got da car and i bought warranty, and i wana make sure ma warranyt doesnt void.....and how hard would it be to change da blowout valves....frum ma old 1 to dis new 1......so just incase ma warranty does void kause of da blwout valve wenneva i have problems i could switch it back to da original 1HELPPP???: flow with the APS blow off valve. As for the fool who reported call would not count, allow him flow purchase a $20 BOV and performance i the diaphragm start up leaking at idle and reason a lot of driving themes.

Q: Mostly suction apparatus with dual head motor, consist a non-return valve, what is its function to have it on the apparatus and not to have it?: It depends on the size and pressure rating as to the material used. Small lower pressure valves can be brass or bronze while larger high press valves will be made from cast steel. Brass can be used for some internals because it is corrosion resistant. It is also softer which makes is good for seating material.

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: I have tried to adjust valves of Suzuki Intruder VS400 but they still tapping..so how to adjust them in the right way?: if okorder and download the free bee manual for your bike.

Q: im having trouble locating the pcv valve on my 1979 oldsmobile. i have a 305 engine. i need to replace it asap, so any help would be appreciated. thanks in advance to all feedback.: On one of the valve covers. It will have a larger dia. (about 3/8) hose hooked to the end up of and going to the carb. It will be pushed into a rubber plug thing on the valve cover. Just remove hose, and grab valve and pull up on it.

Q: I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it???( How bypass valves work): This Site Might Help You. RE: Cold Air intake + Bypass Valve. ? I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07.

Q: i wanna know the role of TOP ENTRY in this definition it's difference with side entry valve.: The ball and seat components enter from the top for top entry ball valves, while the ball and seats enter from the side for side entry ball valves. The top entry features online maintenance without dismounting the valves from the pipes.

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.
