Q:I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.: Shouldn't be a problem. all that's needed is a valve with elect contacts on valve stem. should be able to get one with two sets of contacts for on and off...

Q:Also please tell me why globe valves are preffered for Landing valves in wet risers in firefighting and gate valves in dryrisers..: Robert A has a pretty good answer. A point of clarification. Gate and globle valves can be manufactured of various materials from steel to plastic. I am not sure what a landing valve is but I would expect most valves in a fire fighting system to be gate valves. As previously stated, gate valves are typically open or closed and globe valves are used for controlling flow. You need to view their function in this light in trying to understand why one or the other is used in a fire fighting system.

Q:Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks: A friend 65 and I , age 61, had our mitral valves replaced this year. I felt very tired at first. Barely could get up into a pickup truck. My chest felt stiff with difficulty raising my arms. I slept on a couch with 2 pillows awhile. If I laid down flat on the bed, I could not breathe comfortably. It felt so great to be able to lie down flat on the bed after about a month. I had little twinges in my chest occasionally. It has gradually gone away. After 6 months, I feel great and can do all I could do before surgery. I go to water aerobics 2 times a week and walk my dog. Many people are getting valves replaced at ages 60 and 70.

Q:i want to know where we must use swing check valve and where we must use lift check valve in petrochemical companies. what are the differences ? are they different from the appearance? how can we distinguish between them visually?: Most swing check valves have a external plug on one or both sides of the body where there is access to the shaft. Lift checks do not have this feature. As to vertical operation of swing checks. There are many swing checks that have a restraint feature built into the body so they can operate in either the horizontal or vertical position. The main thing most people over look about check valves is the need for maintenance. The pivot pin on swing checks can wear and cause the clapper to not seat properly. In some services the internals can accumulate material and become fouled. Most lift checks have a spring that can fail and cause the valve to malfunction. This is specially true if the valve is installed in the vertical position. All checks should be periodically inspected to assure they can function properly.

Q:what is the difference between the pinch valve and gate valve / knife valve? If someone can help me explain / show me the complete structure of pinch valve and the way it operates, thats better: a pinch valve has a membrane (or sleeve) inside the valve. When the valve handle is screwed down the membrane is pinch closed. This type of valve is good when the flow needs to be finely controlled. It is also good for slurry (abrasive) flows, as the membrane can be replaced when worn. Gate valves are less effective when the flow must be controlled. They are not used in slurry applications at all, as the gate will be quickly worn away. Knife gate valves can be used in slurry, but are generally totally open or totally closed. The valve must be installed the correct way around, as when closed the weight of the product against the knifegate helps seal the valve. If you have the wrong way around it will tend to leak.

Q:I was looking at the specs on my audi a4 and it said 30 valves and I was looking at a few other cars and they said 24 valves. What do the valves determine? Whats the difference if the car has more valves than another?: Valves let the air and fuel in and the exhaust out. Number doesn't matter much, seeing as some valves are bigger than others and overall what really matters is the bottom line which is power and efficiency.

Q:I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :): Valve = Steam. Research Steam and you research Valve.

Q:I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??: MVP is rarely life-threatening, but the best way is always to follow doctor's guidance. Sex would not be a problem with MVP. MVP can be treated with medicine, surgery, or both. Medicine For people with MVP who have little or no regurgitation, medicines called beta blockers have been used to treat symptoms such as palpitations (strong or rapid heartbeats) and chest discomfort. For people with MVP who have significant regurgitation and symptoms, the following medicines may be used to prevent complications: Vasodilators to widen the blood vessels and reduce the workload of the heart. Examples of vasodilators are isosorbide dinitrate and hydralazine. Digoxin to strengthen the heartbeat. Diuretics (water pills) to remove excess fluid in the lungs. Drugs such as flecainide and procainamide to regulate heart rhythms. Anticoagulants (blood thinners) to reduce the risk of blood clots forming in people with atrial fibrillation. Examples include aspirin or warfarin. Antibiotics to prevent infective endocarditis, an infection of the surface of the heart valves. Surgery Surgery on the mitral valve is done only when the valve is very abnormal and blood is regurgitating into the atrium. The main goal of surgery is to improve symptoms and reduce the risk for heart failure. The timing of the surgery is very important. If it's done too early and your leaking valve is working fairly well, you may be put at needless risk from surgery. If it's done too late, irreversible heart damage may have already occurred. Good luck to you.

Q:i need exhaust valves material dimensinons of any car.: Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.

Q:I accidentally pushed the pressure release valve on my hot water heater last night. It ran for a while, and did not stop. I turned the water off, the valve on the cold water piper above the water heater, and it stopped running. Will this stop running at some point? The overflow tray fills too quickly for me to drain it. When I turn the water back on it starts pouring out again. HELP!!!: the device once activated rarely reseals It is called a TP valve or temperature and pressure they cost about 15 bucks at the big box stores they usually have a pipe attached to them and are plumbed outside you will need to cut the pipe and unscrew the fitting attache to the TP Now remove and replace the TP make sure to use tape or pipe dope Do not touch the valve in the future reinstall the pipe and solder the pipe back together using a coupler
