Q:Is it ok to reuse valves?
If okorder.com/
Q:Is my water valve broken?
Could be a 3-way valve. Try putting it back in the middle. If that doesn't work, it probably broke.
Q:Replace Heater Control Valve Honda?
You have to take the whole dash apart. Not an easy job, and definitely not one for a novice.
Q:Where can i find a three-way air pressure valve?
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q:what do the valves of an engine do?
The intake valves allow a air/fuel charge to enter the combustion chamber, the exhaust valves allow it to leave. They need to close and seat properly so when the piston comes up on the compression stroke there is plenty of a compressed air/fuel charge for a strong combustion. Without this compressed charge you will have a little fire in the combustion chamber and not an explosion.
Q:valve adjustment?
w/ one hand spinning the pushrod and the other tightening the rocker arm nut, tighten the nut until you can not spin the pushrod freely, then tighten it three quarters of a turn more. do this to all of the rocker arms that do not have pressure against the valves, then spin the motor 180 degrees, or until the rest do not have pressure against them, and do the same thing.
Q:ac replacement valve?
The valve itself is only a couple dollars. Some shops have a tool that will let them replace a valve without dumping the charge but since its likely low you will likely also have to pay the regular AC service fee which is usually $50-100 plus parts and refrigerant.
Q:Leeky Aortic Valve Questions?
Valvar insufficiency/regurgitation that is a result of surgical repair of a congenital defect does not self-resolve. It's not clear what your initial diagnosis was, however I would guess that you were born with aortic stenosis. Balloon enlargement and/or surgery to repair a stenotic valve almost always results in some degree of insufficiency/regurgitation. A small amount of insufficiency/regurgitation is much better tolerated than stenosis. It is a tradeoff we accept for improved patient outcomes. Really, the answer to your question is dependent on a multitude of factors, the most important of which is the degree of insufficiency/regurgitation you have (i.e. trivial, mild, moderate, or severe). This is really a great question and you deserve a full explanation. However, I cannot give you a factual answer without more information. You may also have a bicuspid aortic valve, which opens up a whole other set of variables. One thing I am sure of, however, is that you will require the care of a cardiologist for the rest of your life. It's possible that later on you may only have to follow-up ever 1-3 years, however, it will forever be necessary to properly monitor your valve and its effect on your heart, not to mention any associated problems you may not be aware of that become a risk with age. Good luck.
Q:Valves and cylinders?
For basic internal combustion you only need two valves, one for intake and one for exhaust. The four strokes are referring to the piston moving up and down in the cylinder, one to take in gas and air, one to compress the mixture, one during combustion and one during exhaust. Common cylinder amounts for cars are 4, 6, and 8. Some Volvos had five cylinders, and exotics can have more than 8. Modern engines can have more than two valves per cylinder but the standard is still two, so if you have 12 valves you most likely have a 6 cylinder engine.
Q:Which valve type is commonly used at ship's sea chest suction (inlet) side?
Gate valve is commonly used.
