- Q:what are the factors should be know to select a control valve for specified application
- There are numerous articles online that address this question from choosing the correct size to the correct actuator. Here are just a few:
- Q:Among butterfly,ball,needle and gate valves which is used mostly in pneumatic system?
- It depends on what sort of system you are operating. Most butterfly valves leak, a few don't. Ball valves are instant operation, and don't normally leak. Needle valves are used for fine control of the flow rate. Gate valves are quick to operate, and don't normally leak. On aircraft pneumatic systems, butterfly valves are common, where a leak is permissable. Where no leak is permissable, slide valves are used, which have rubber seals.
- Q:I had to replace the gaskets on my valve cover only to discover that the valve cover had developed a hole due to oxidation. I waited a week for a new valve cover to come in and left the engine exposed. Should I have any issues? I mean its covered but its still outside. Should I pour some oil on the exposed part of the engine?Its been already about a week.
- yea it will be fine as long as you check the level and watch for bubbles of water on the dipstick after running it a bit, just change the oil and filter to insure you don't water foul a plug
- Q:What is the easiest and best way to fix a leaking shut-off valve on a toilet?
- Replace it there fairly cheap.Usally all you need is a wrench an pipe thread tape and a new shut off valve bably less than 20 bucks total.Just turn off the water an flush the toilet.Place a pot under the connection so it will catch any remaining water as you loosen the connection.There are 2 large nuts at each end of the shut off valve.Turn them conter clockwise to loosen an clockwise to tighten.Wrap the threads with pipe thread tape on both ends before installing the new shut off.Its probably one of the easiest do it yourself plumbing jobs there is.Once you have the new shut off installed an tightened turn the water back on an check for leaks.If it is leaking you may have to tighten your connection a little more.Good luck,I hope this helps.
- Q:please i want theory of MOTORIZED VALVE ? COURSE TITLE : MEASUREMENT AND CONTROL EXP. TITLE : CALIBRATION AND CHARACTERISTICS OF MOTORIZED VALVE
- Valves Either control valve or shut off vales operated by electric motor is called Motorized valve. Close the vale see it is closed Open the vale at different positions say 5% 10% 15% etc and see the control signal and the actual opening.
- 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:Exactly what is an EGR valve where is it located?
- EGR is exhaust gas recirculation. Nothing more than to help out the environment. Simply puts exhaust gasses back through the motor to reduce (NOx). Since the exhaust gas is very stable (inert) it will not burn again, lowering combustion chamber temps when introduced. As mentioned it is a ufo looking piece, usually located in the engine bay where it can be seen.
- 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
- Well, the biggest risk you may have upon getting a tattoo is an infection. And of course if the tattoo is done at a reputable licensed shop the chance of getting some sort of infection or virus from the tattoo equipment is minute. The biggest chance you would have of an affection is during your after care. You are at no greater risk than the next person of getting an infection. But, if you do get an infection could be worse consequences. I will never advise someone to against what there doctor tells them. But if one doctor says it is ok then the next says it is not then maybe tattoos and piercings are just something that doctor is not fond of to begin with and allowing his personal opinions influence his medical direction or counseling. In the end it is your body and it is your decision. Should you take extra precautions? Sure. See if you can get some antibiotics prescribed and begin taking them a couple days before getting your tattoo. Tell you are planning a visit to the Dentist and have prescribe some antibiotics for you if you decide to get a tattoo. If you do, be sure to follow the artists instructions on after care procedures and to be sure to ask any question of him you may have concerning after care.
- Q:Can a dirty or faulty EGR valve cause overheating. My 2001 PT Cruiser is overheating but only on very hot days and when the air conditioning is on. Back flushed and pressure tested the radiator, changed the thermometer, fluid was low but doesn't seem to be loosing fluid since refilled. Check engine light came on and indicated poor air flow through the EGR valve. Is it worth replacing prior to pulling the radiator to check that for the problem with overheating? Mechanic I trust doesn't think the EGR can cause overheating.
- No it won't. A attempt to work out if the egr is working outcomes interior the different. while the egr is activated (at idle) the rpm's will drop extensively by way of an over wealthy blend. The overheat is being led to by ability of a few thing else. For the over warmth- verify your coolant point - verify belt tensions - radiator blockage (inner and exterior) - water pump impeller may be loose. may be time for a timing belt besides.
- Q:im looking at buying a 1995 ford probe, but it has a busted valve in the head, does anyone know how much it would cost to have fixed?
- stay away from it
