Q:1+ Tricuspid/Pulmonic valve insufficiency?
grade 1 murmur nothing to worry.
Q:3 way valves?
A three-way valve on a chiller increases efficiency by allowing return water to mix with a small amount of the water being supplied to the loop. These valves are sometimes mechanical to allow water to recirculate through the chiller to keep the chiller running during low ambient conditions. A pump shut off pressure, is the pressure at which the pump control turns the pump off. If a system needs 60psi to run efficiently, the pump control will be set at 60psi.
Q:Can I take a reversing valve from a heat pump.?
it depends on the unit but you can run it without the heat pump..somtimes its the solenoid and not the actual valve body that can be replaced without recharging.check the current to the valve first.
Q:EGR Valve question...?
It recirculates the fumes and the air--but a cracked hose is a nightmare if vacuum leak develops--fix it--just get a new hose and happy motoring
Q:trucuspid valve... pulmonary valve??
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:confederacy of dunces: ignatius's valve?
Most Premature ejaculation problems in a young man are usually due to stress or fatigue, and rarely if ever a reflection on the partner. So you need to take yourself out of the problem part of the equation. It's also not a trick pony that performs on command, despite what some folks think. And anxiety will only provoke the problem more. You two could certainly use some help, as far as what you center your attention on.
Q:Trumpet valve stuck upright?
on the top of the valve there is the screw that you turn to open the valve to oil it. if this screw wont turn gently tap the edges of it with the rim of your mouthpiece, and make sure that you get the entire screw cap. if this doesn't loosen it enough to remove the cap, then repeat while hitting it at an angle in the direction that it needs to turn. if this doesn't work take off the bottom cap and drip valve oil up though the bottom to drip up to the top cap and continue with the tapping process. if it still wont move, you need to take it to a shop. once the upper cap is loose, the valve still wont move, this is when you take off the bottom valve cap (if you haven't already) and fully remove a different valve that has already been oiled and push it up through the bottom of the stuck valve, this might be hard to do, and you might need to put in a lot of valve oil into the bottom to get it to move. once this valve is removed, thoroughly clean the valve casing and the valve itself, and oil both before replacing the valve. Hope this helps.
Q:Whats the difference between Steam and VALVe?
I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve ( is a legal company, same as meaning the link I put there. Hope it helps! :)
Q:Can faulty valves cause high oil consumption?
Valve guides and seals will, but not the valves. Bad valves will lower compression on the engine and reduce performance but won't burn oil. The deposits on the valves are most likely from oil burning, getting to the heads past the piston rings. The rings aren't hard to change if you already have the head off... pull the cylinder block off and the pistons will be accessible. Getting the block back on can be tricky as you have to get the rings compressed. Might take two or three people. Good luck. Reassembly is harder than disassembly, but you probably already know that. Make sure you get the cam marks exactly right!
Q:Looking for a BBb 6 valve tuba?
I don't know how long you've been playing tuba but 6 valve BBb tubas are virtually non-existent. No current brass instrument manufacturer will have that in their line-up. Tubas with 6 valves are already rare and are pretty much limited to F tubas. If you want a 6 valve BBb (I don't know why you even need/want that many valves) then your best option would be to buy a 5 valve BBb tuba and having it modified to include a 6th valve. Either way, expect to pay a minimum of $10000 (ten thousand) for the instrument.
