Q: i have a valve seat pop out and it did some damage my question is can it be fixed i took it to a machine shop the guy look at me with a little confusion he said it cant be done anyone out there have another answer: In most cases it can be repaired. You just need to find a machinist who knows what he is doing. Call some local VW shops and ask who they use.

Q: There has been brake fluid leaking below where the Master Cylinder was and pinpointed that the leak was at the base where the steel lines and proportional valve intersect(kinda sprays out out like if a seal is bad or someone didn't tighten enough). Any way to fix this or replace? Vehicle is a 1988 Plymouth Reliant (2.2 liter) Auto, no ABS.: If you are not familar with brakes I wouldn't suggest tackling this job yourself. You will need to take the line off in question to condemn either the prop valve or the line. I have never in my life seen the line itself leak but I guess it's possible. The valve is a dealer item only, whatever you do, dont buy it from a junk yard. After replacing the valve, if that is what the problem is, most likely you will need to get a brake power bleeder to get all the air out of the system. I would estimate through a shop and the typical mark up on the part, shouldn't be more than 200-225 parts and labor including the brake flush, good luck.

Q: what's the differences of American standard valve standard and Europe valve standard.Like API598 and ISO5208 , EN12266 valve inspection standard, or API600 valve design manufacture standard,and EN598,: the name itself suggest that it isn't. BSP covers only pipelines but ISO is a standard concerning different materials, processes, programs and quality policies.

Q: ok im buying a kx 125 from 96 and he said the only problem with the bike is that it has a small oil leak around the power valve too me it sounds like a gasket. but i want someone elses opinion on what else it could be.: The kx125 actually has 3 valves in the exhaust, a main, a left-hand one and a right-hand one. Each is fitted with o-rings which require disassembly in order to be reached. This would also be a good time to clean the power valves since they tend to become encrusted with carbon deposits which interfere with their normal operation.

Q: have a 86 flhtc had new cylinders 10-1 pistons supposed to be 86 cubic inches when i run it up to 90-95 bending valves what can i do to stop bending valves-------HARLEY DAVIDSON: I'm leaning toward the valve float or lifters pumping up idea. I wouldn't double up the head gaskets because you're asking for a leak, especially with your high compression. A good way to determine how much actual clearance you have between the piston and valve is to stick some soft modeling clay on top of the piston where the valves are, torque down the head, turn the engine over and take it apart. You will then be able to measure how thin the clay was flattened out to, giving you an idea of the clearance. If you seem to have plenty of clearance, then it may be valve float. If you've swapped out the cam, also compare the timing as well as the lift. The actual lift may not be a problem, but if it's opening sooner or later than stock, that may be when the valve and piston collide.

Q: this valve used in the refinery.: This is a 'Trip and Throttle' (T T) valve that is maintained in a 'Fully Open' postion during normal turbine operation. It is maintained open by a Hydraulic Control system that, should any of many shutdown conditions occur, the hydraulic oil will be dumped to its reservoir by the operation of a Solenoid valve, actuated by the shutdown signal, and the T T valve will immediately close, stopping the steam flow to the turbine speed control steam chest in a safe manner. The valve handwheel is then operated to ensure that the valve remains fully closed until the system is ready for re-start. The valve cannot be opened again until the shutdown condition has been rectified and the hydraulic system reset to restore the oil pressure to the valve. The valve however, can then only be re-opened manually and slowly until the turbine is brought to the 'Minimum Speed Control' Governor setting. When settled down at this condition and the steam chest valves are under the control of the Governor, the T T valve is swung wide open. This latches the valve in the fully open position until another shut down occurs,

Q: why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?: Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.

Q: I see a valve that says FNW on it with ( on, off ) but I'm not sure it's the main valve to the water supply. It does go to the water heater so I'm guessing that it's it. Does anyone know anything about the main water supply valve and how to find it?: The valve that goes into the water heater is usually the cold water into the heater. It will shut off all the water in the house, but to make sure you should turn off the main valve. If it's an older house, this the valve into the the heater is generally the main valve, otherwise it will be located near the meter and most commonly on the house side of the meter.

Q: I am a junior piping engineer. I want to know what is the meaning of term Triple Eccentric in Triple Eccentric Butterfly ValveButterfly Valve. So kindly enlighten me.: Above answers your question. I've used these and they work great. But they cost much more then your tradition quarter turn butterfly valve.

Q: i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?: If the car gets to sit for several hours that should not be a problem. Otherwise give the other paint 72 hours to dry hard before removing the valve cover. You may have to rag it a bit. Use hi-heat paint on the covers.(follow directions on the can)
