Q: What are the requirements for valve automation?: Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.

Q: I have replaced the rubber washer in the valve and when I pull up on the float arm everything seems to stop then shortly thereafter air bubbles start coming out of the bottom of the fill tube. How could air be getting thru the valve without water which would cause the shutoff valve to tighten?: air in supply line

Q: I have an old trumpet valve stem that will not screw in the valve cap. I ordered a new one but I'm not sure how to remove the old one and put the new one on without doing anything that would influence the look and playing. HELP!!! Professionals are welcome and others. I don't have any professional technicians near by .Summer band is starting up so I need this FAST.: I hope you have a Bach trumpet, because each valve stem is specific to a particular maker and even to specific models. So, if you don't have a Bach trumpet it is very likely that the stem won't fit. If you cannot remove the valve stem with your hands you can try soaking the joint with oil and/or warm water and dishwasher detergent. You should give yourself a couple of days to see if you can loosen them up. Do not use tools--no screwdrivers, no pliers, no vices, no strap wrenches--if you don't know what you're doing you stand to damage the very fragile valve. You may need to take it to a tech--remember you're trying to avoid a $100+ dollar bill for repairing a damaged valve.

Q: we are researching fluid power (pneumatics and hydraulics) in my high school engineering class. Does anyone know another name for a valve? I've been able to find different types, but I can't come up with any different names for a valve. Anyone have any ideas?: Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.

Q: I need an angle valve for my sink buts its a bit of an odd size. I have copper tubing at 1/2 i need a valve preferably compression that can feed to a water supply that is 1/2 Pipe thread.Included images of the supply hose valve to sink. To help show what i'm looking for.: If you're looking for a valve that attaches to a 1/2 iron pipe coming out of the wall, and then will feed to 1/2 copper tubing, then you're looking for- an angle stop, 1/2 female iron pipe to 1/2 compression. Just about any good hardware store will have it in stock or be able to order it, just be sure that they know what you need. I've often found that using visual aids,like a piece of pipe in one hand, and a piece of tubing in the other, with an empty space, waiting for a valve, between them, can be an invaluable aid to communication. Don't even try to cut and adapt a braided hose. The stainless braid contains a (relatively thin) rubber hose. Without the braid to reinforce it, it will burst. If you need to adapt plumbing, there is always a way to get water from point A to point B. The challenge is finding the most elegant route.

Q: How do I know if the valve seals need replacing? From what type of smoke can I detect?: A 'leak-down' test is the best bet, shows where in the system the compression is leaking and if it's around the valve stems than for sure the seals need replacing. Can't judge it by the smoke accurately as oil could be slipping past the rings also.

Q: my check engine light tells me that i need an egr valve, if i install one will that cut the light off????: Possibly. If you don't go out then you need to have someone hook up a code reader and clear the SES light.

Q: I had heart surgery a little over a year ago. This surgery gave me an artificial aortic valve in replacement to my real aortic valve. Before this I smoked weed all the time, but now, I 'm on blood thinners, and I'm not sure if it's okay. Is it?: Definitely not recommended to do any non-doctor recommended drugs while in such a state.

Q: and describe the direction and type of blood (oxygenated ot nonoxygenated) that flows through this valve.: Mitral valve has two cusps. The blood flows from the lungs, where it is oxygenated, into the left atrium then through the mitral valve into the left ventricle. From here it flows through the aortic valve to the rest of the body. Two cusps, oxygenated blood.

Q: How do you take out a valve stem?: No. The cap just keeps dirt, debris and moisture out of the valve stem and core. If you remove the valve core (it screws out with a special tool) then yes, your tire will go flat in a big hurry. To remove the complete valve stem as a unit there is a tool that screws on to the end that you can use to rip it out of the wheel. A new stem has to then be inserted from inside the wheel requiring the tire to be dismounted.
