Q:We've got a one-handled faucet for the tub/shower and it has that pressure-balancing mechanism. We have it set, I think, so that we can take the hottest showers possible, because our water heater lacks enthusiasm. However, when I want to draw a bath for the baby, I need it to be lukewarm - and I have to turn it almost OFF to get the water to be even tepid. I can't get cold water out unless it's only trickling. As far as I can tell, our cold water pressure isn't different from the hot (bathroom faucets are 2 handles and H C seem to be about the same pressure). Is there a way to adjust the valve in the shower so I can get both the hottest possible, and the coldest possible water at full pressure?
All major manufactures of valves have excellent customer service departments. Most of them also have great websites with lots of technical info. Note: You may try changing your shower head to one that is a higher flow or remove any flow restrictor that may be in the one you have now. This may allow you to have the valve set to a colder setting for the tub spout and should increase the hot when showering. Personally, I don't like these style valves. Too many problems like yours.
Q:I got a 2012 peterbilt 386 ...it just came back from the shop a few day ago to get injectors 4 and 5 looked at and repaired ....I'm getting a fault code for injector spill valve and a engine light ....I tried resetting the computer to get rid of the code but that's not it ... uld timeing of this cause the problem ...but other than that it runs like a champ so what could I do to fix this is it time cause I did probably get re timed when they repaired it
The fault for the spill valve is not something you can correct with timing. When they repaired or replace injectors they need to be programed into the computer so they match the other injectors. The spill valve is in the injector and is there to return unneeded fuel back to tank. If this valve does not work you could be over fueling or run the risk of fuel cooking in the injector making a mess of the spray pattern. It should be telling you which injector is throwing the code and if it is one of the two that were worked on take it back.
Q:Can someone please explain the difference between a pressure tap valve and a gate valve (if any).
this will explain about a gate valve e
Q:I took my 2nd valve out to wash it (i couldn't find my oil, but it worked fine) and I've tried making the number face the mouthpiece, yet it still is messed up and won't let me play a lot of notes.
1) Try this first and if this doesn't work, go to #2. Oil the valve's body and gently put it back into the cylinder without screwing it in yet. Then, turn the valve until it clicks, and make sure it is really seated correct. Some trumpets have two clicks, and one is not the right one. So, you have to get the right click - which tells you that your valve is seated right. When your valve is seated right, then screw it in. 2) If you don't get a click when you spin your valve - look at the tubing on your trumpet and line up the holes in your valve with the tubing. When the valve is up, it will line up with 2 holes of the tubing, and when it is down it will line up with 2 other holes in the tuning. So, you can determine the correct positioning of the valve by looking at the tubing on your trumpet. But this is a last resort. I've never seen a trumpet where the valves don't click when you turn them.
Q:Where is the PCV valve located on 2001 Nissan Altima
either in the intake or the valve pan.
Q:compare the structure of the tricuspid valve with that of the pulmonary valve??please help me
Hello Inga, I'll help you this way. Form Follows Function. Remember that as you learn anatomy. It will guide you, make sense out of confusing things. In this instance, those two valves are not the same. They have very different requirements. Understanding the structural functioning of the heart will make this clear to you. Go back to the text, reread this section. Ask yourself. What are the differences between these compartments? Once you've an understanding of the cardiac cycle. You'll see ( hence remember it) for yourself.
Q:how to get adjust the valves on a craftsman mower with a briggs and stratton with ohv 18hp? Iv'e heard you adjust them around 5 thousands with a feeler gauge. But im confused about what position to adjust them. Iv'e heard you wait till one of the valves is closed while the other is open and adjust that one. Then repeat till you got them adjusted. Whats the proper way?
when a valve is closed there should be a gap under the valve stem and push rod that's the adjustment, when a Valve is open the push rod is against the valve end so you cant adjust it while its open i would set them at 10,thousands to allow for heat expansion
Q:First off I'm a girl. :) My 2.0 non turbo engine has a bent valve. I have been asked to pick up the valve. But I need to know if its for the intake or the exhaust. I know the guy how is going to fix it said he will have to sand down the cylender that it goes in it. The car sounds like it knocking when driving or sitting still. The guy who is going to fix it is at work right now and I'm suppose to order this part right now. Is it an intake or an exhaust valve?
no way to tell ...and he doesn't sand down the valve ...it's called seating or lapping. and it's not done to the cylinder... knocking could aslo be a hung lifter.
Q:What are the types of control valves used in the oil industry and how are they applied.
There are other manual control valves and on/off automatic valves that are used a various places for remote or emergency control. These can be globe, gate, ball, plug or butterfly valves. They can be actuated by pneumatics, hydraulics or electric power.
