- Q: Hi....my boyfriend is currently waiting to have heart valve replacement surgery and im a little worried about the whole thing...he doesnt like talking about it but if someone knows the answer to my questions I'd be so greatful!!First of all a little detail....he is 19, as far as i know he was born with this problem with his valve but it has got worse over time. he was also born with a hole in his heart but had an operation as a baby to fix this. he gets short of breath and often has pains in his chest. he says hes going to have a pigs heart valve to replace his, by open heart surgery (in a few months time). my main worry is whether the operations are always successful? and will this condition/operation affect his life expectancy??please if there are any experts in the field help put my mind to rest....!thanksshelly x
- Open heart surgery is always a risk, as is any major surgery. The main risks are from infection and blood clots. The risks taper off very quickly within a few days after the surgery. Heart valve replacements are a common operation, with a high success rate. Life expectancy is generally better with a valve replacement; but not all valve problems reduce life expectancy to begin with. Sometimes the trade-offs are more of an issue with quality of life, with higher quality achieved with a functioning heart valve, so some people may be taking a medical risk to obtain higher quality of life. No one can tell you for certain what the outcome of this operation will be. The odds are very high that everything will go perfectly and he will fell better than ever before. There is a very small chance that he will end up worse To put the risks in perspective, a person i know had minor surgery to her knee - a simple 1 hour operation done at an outpatient clinic. Ten days later, a clot broke loose and she died in her sleep. I have had the same operation twice and didn't even miss more than a few hours of work. Another person i know had severe heart problems and docs said it was terminal, but an operation could prolong his life maybe 5-7 years. He had the operation and its now been almost 20 years and his cardiologist says his heart is healthy and there's no reason why he might not live another 20 years or more.
- Q: My question mainly pertains to Electric Motor-driven Motor Operated Valve Actuators.
- It's been a few years, and I think it depends on the size of the valve, but: I think there is usually an electric motor, maybe 1HP or less, connected to gears and a valve actuator which might actually move a valve stem. Limit Switches (LS) usually stop the motor at the ends of travel, and provide signals to outside control systems. So maybe somebody somewhere pushes a button to start the motor, and it runs until the limit switch opens the circuit and stops the motor. To move the valve the other way, they reverse the motor.
- Q: I have a training I will be attending on Valve actuator and subsequently an exam. I need fundamental knowledge of ROV. What are the types of ROV. The Maintenance Of ROV ? and the different Type of ROV actuators
- I would assume the nitrogen is stored under pressure and it used to pressurize the hydraulic system and the hydraulics in turn operate the valve by driving a piston as required by an electrical signal. This can be a fairly common system for such operations. The electrical signal can be triggered by either direct electrical contact or by an electronic signal depending on the design of the system.
- Q: I did a compression test, and I have a broken valve. everything else is in perfect condition besides this valve and I have carbon getting built up in one of my pistons. Can I run the car like this? What cause this from happening what was the cause age?1999 Ford Explorer 4.0 OHV with 146k,miles
- you cant drive w/ a broken valve lying around in the engine. but yes you can drive w/ carbon build up, it causes the engine to run a lil warmer and prolly acts as a oil seal to the piston even after the rings go out.and youve ran a lot of gas thru in 12 yrs so carbon build up is normal,valves dont always break tho unless you were giving it hell an it jus seen so much wear an got thin an finally broke.mayb its not jammed into the head and its jus broke
- Q: I went to turn the water off with the shut-off valve so that I could do some work on the toilet tank (replacing old and leaky fill valve) but the water won't shut off. I'm assuming that I'll need to replace the shut-off valve itself but could anything else be causing the problem? The funny thing is, the leaky fill valve that I wanted to replace has now stopped hissing and leaking and the tank seemingly fills fine. But of course the water can't be turned off completely.Just wanted to check make sure that there aren't anything else I should do or consider before I went off to replace the shut-off valve.Thanks
- the shut off valves are soldiered on or threaded on it depends on which 1 you got. it might be easier to get a valve that looks like yours and putting the guts out of the new 1 into the old 1. as long as you can shut the water off to the valve
- Q: I was wondering if anyone knew how important tire valve stem caps were in maintaining inflation pressure in auto tires? I noticed one of my tires losing air slowly (from 30 psi to 21 psi in about a week) and this tire (unlike the other three) also had a missing tire valve stem cap. I've just replaced it, and was wondering if a missing valve stem cap caused faster loss of tire pressure.
- Tire valve caps are the final seal again potential failure in the valve of the valve stem. A good tire valve cap will come with high quality rubber seal that push against the circumferential 'ring' of the valve stem and thereby help to contain the air should the valve fail or not containing the air very well. You observation of your tire (the one with the missing cap) losing air confirms that this could be a possibility. Of course, the other possibility is that your tire is having a slow leak - go to any petrol station, and it could be rectified at a minimal cost. Note: Even if the valve is perfectly good, if the tire go over a bump or pot hole, it is still susceptible to lost of air due to the additional pressure asserted during the hit.
- Q: -air pressure of 40 psi only -run on 12v or 250 vac-no need for half open or any of the options i just want it on or off-it will be for a costum use so i dont need any special designs for it any thing will work -it also can be change from gas to water if

- Q: Could my subs kill my EGR valve? I replaced my O2 sensor and my check engine light didn't go off. So I had it checked again and the same problem was still there. It said that all the cylinders were running either rich or lean..... I can't remember. But I was told it could be the EGR Valve so I replaced it and for about a week the check engine light was off.Now its back on. Had it checked again and the same deal was going on. Oh there was also a low voltage reading..... which is why I'm thinking its my subs.So could it be my subs that keeps killing my EGR valve? And any solutions will be helpful. I don't want to have to replace my alternator because its in an extremely tough place to reach. And I already have a small Cap.... .5. My subs handle 600 RMS total. WOuld getting a bigger Cap help?
- next time state year/make/model/mileage. most egr valves operate via vacuum. your subs can't affect a vacuum operated egr valve. if the o2 sensor didn't help out, you probably have a bad vacuum hose somewhere. that will cause the system to go into havoc because the car computer can't compensate for the excessive air being sucked in. a cap does not help with anything except for a loud THUMP. the THUMP causes a voltage spike and stresses the charging system. the cap takes care of the thump safer, it's not a complete solution.
- Q: Defects in which valves would produce the following?1) SEVERE DEPENDENT EDEMA?2) PAROXYSMAL NOCTURNAL DYSPEA3) CONGESTED LIVER?4) DISTENDED JUGULAR VEINS?5) PRODUCTIVE COUGH WITH FROTHY SPUTUMfor 1. i believe it's tricupsid valve, 2. mitra valve please correct me if I'm wrong. Thaanks!
- Tricuspid regurgitation: Symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension.
- Q: I am looking for a full valve guitar amp for around ?300.It needs to be loud enough to play with a quietish drum kit.Currently i have looked at an epiphone valve senior in both and combo and cab and head form. i have also looked at some smaller amps such as the vox ac4 but am a bit worried about its small size. any advice would be greatly welcome. many thanks in advance.
- Well I have the Valve Jr. and the AC4. The AC4 is a good sounding amp, but even though it is only 1 watt less, the Valve Jr. is much louder. The AC4 is a great practice amp but not enough to jam with a drummer unless he is pretty quiet and you really crank the amp. Never heard one of the new Valve Sr. models but with all of the goodies they added it should sound really good. I had my Jr. modified but it still doesn't have all the cool stuff the Senior has. I think you would really like the Epiphone and at 20 watts you will be more than loud enough. My 5 watt Jr. will get very loud. All I own are low watt class A valve amps, it's the only way to fly!! The Marshall Class 5 might be worth looking at also.
