Q:used in pipe line: Bellows Relief Valve

Q:i am hearing tapping on top under of vale cover sound like valve need adjusting: time to change oil, use thicker oil or yep, adjust valves. not a monstrous project but time consuming. Need torque wrench, valve cover gasket and shim kit to adjust. It's a pain as u have two nuts on each valve adjustment rocker bolt. tightening causes the lower one to drop sometimes so u may find yourself adjusting the valves 2-3 times each. I did it on my old Acura with 78K miles. ran smoother. i dropped in a pulley kit and cold intake as well but afterwards. the head was real clean as I change oil regularly. I had tapping even after changing the knock valve so I knew the valve job was needed.

Q:What's the safety valve (relief valve) type?: The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.

Q:If I flush the toilet the drama begins. While the toilet is flushing, if I lift the lift of the lid of the tank cover NOT THE SEAT, water shoots up straight in the air from the top/cap of the fill valve. This is a picture of a toilet fill valve.: They okorder /

Q:hey...im kinda confusedis cochlear an artificial valve???and if not..what is an artificial valve??: Cochlear implants aren't valves, they're implanted behind the ears, they improve hearing in people who are hard of hearing. An artificial valve replaces a heart valve, which controls how much blood flows in and out of the heart.

Q:does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?: Yes they do go bad! It sounds like that is your problem. You can try bleeding the proportioning valve with a brake bleeding gun, making sure to open every valve then re-bleed the brake system this will eliminate the possibility of a air bubble in the proportioning valve. I have changed probably ten or twelve of these things in my ventures.

Q:what is the average cost to replace a valve core on a car? also can any car shop do it or do i have to go to a conrads etc.: You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.

Q:Hello,I've not found a perfect fit using a solenoid valve for gravity fed irrigation system. Primarily because it requires a constant drain on the battery while the valve is open. Is there a motorized valve to fit the bill? One that momentarily requires electricity to open and close the valve at 12v DC or less to work in gravity fed system?: I don't know how it specifically wires. There are two strategies for latching devices. One is a solenoid with two coils. Pulse one to open, pulse the other to close. The other strategy is to have one coil. Apply polarity in one direction to open, in the other to close. I suggest googling for latching solenoid valve, and/or checking out the major irrigation (or sprinkler) manufacturers for their offerings.

Q:Is what-valve spring. orvalve guide. orvalve cover. orretainer clip: valve guide. I assume we are taking about an overhead cam engine? the valve guides are the channel that the valve slides up and down in. And are supposed to prevent it from moving side to side. They are also one of the causes of high oil consumption because when the guides where out the oil simply pours into the cylinder.

Q:like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?: Take the head to a machine shop you have to grind the valves or replace then,Same with the seats Then replace the guides and adjust the valves Not a driveway Job
