Q:Water shut off valve?
The water shut off valve is located where the pipe enters the house from the city water main. Maybe on the outside wall of your house near an outside faucet. Or maybe in the ground under a cover plate near an outside faucet, or maybe in the basement near where the pipe comes into the house from outside. There is also ususally a valve out at the water meter. The valve at the hot water heater just shuts of the cold water supply to the hot water heater, so it only effects the hot water.
Q:what type valves 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:what does a Pneumatic valve do in a process?
pneumatic valves use pressurized gas (Air, nitrogen) to operate.A simple example if you are monitoring the level of a vessel in a process the indicator for level (LI) tells you remotely what the level is. If you need to keep the level stable the level indicating controller (LIC) sends a signal to the regulator on the Pneumatic Valve which provides air to open or close the valve depending on what the vessel level set point is. the FIC (flow indicating controller) PIC (pressure) TIC (tempurature) are all instrumentation used to compare a set point parameter against a measured process variable and send a signal to control the valve to maintain the set point
Q:How do i take my valves out?
It can be different from car to car, look up tutorial's on google and youtube for your specific car
Q:homeopathic treatment for mitral valve leakage?
There is a significant amount of scientific evidence that mitral valve prolapse (leakage) is caused by magnesium deficiency. It is therefore treatable by proper magnesium therapy. Below is a link to the world's leading research journal on magnesium and a paper on this issue. www.ncbi.nlm.nih.gov/pubmed/15945... Best wishes and good luck.
Q:Whats wrong with my trumpets third valve slide!?
umm i'm not sure, cuz i play the clarinet but try tighning the mouth peciec and make sure your forming your lips right. then go to the place you bought it or you local music store to find out what's wrong. good luck and Merry Christmas!
Q:What are these valves on top of my compressor?
The valves are probably one way check valves and the line is called the discharge line. The valves could also be un-loader valves that release the head pressure when the compressor shuts off. For parts just google your compressor brand and model for parts dealers.
Q:what happen when solenoid valve is activated?
If the pressure in any one zone is different than the other zones it could be one of two reasons; either the pressure is high (usually due to one or more sprinkler heads not poping up), or its low (usually due to a leak in the pipes). Something that could cause low pressure in all the zones are an obstruction in the water line above the valves (unlikely), or a hole in the line above the valve (the water would be filling the valve box and causing damage to the lawn wherever it is located), or leaks in all the lines (again would be easy to identify from the excess water in the ground at the source of the leak). Lastly the valve itself could potentially be faulty. The solenoid inside the valve holds the valve open when electricity is applied across it. If the wires to it are damaged; if the solenoid is bad; or if the valve has any rust or dirt inside that could cause a lower than normal amount of water flow.
Q:How is a pig hearts valve used to replaced ours?
now days there are vavles used that are man made
Q:Head gasket and Valve cover gasket the same?
LOL. No. You don't get away that easily. The valve cover gasket only keeps oil from splashing all over the engine bay. It literally covers the valves, sealing the engine interior away from the general environment. Th head is the part of the engine that the valve cover sits on. It contains the valves, and either the camshaft or the rods that lead to a camshaft deeper in the engine, and of course the rocker assembly. You have to remove all those big bolts along the casting to break the head free, and you'll need a torque wrench to get the pressure right when you're reinstalling it. The head gasket seals the tops of the cylinders [incorporated in the bottom of the head] to the cylinders themselves [bored into the block proper.] Have fun!!!!!
