The purpose of the valve spring is to close the valve when the cam has finished pushing it open to allow fuel/air in or exhaust gases out.
The spring is held in place at the top of the valve by a split-collet, like 2 halves of a cone, and also sits against the outside of the cylinder head.
The spring is compressed when the cam on the cam shaft pushes it down, and as the cam moves away, the spring forces the valve shut again.

On a big rig where is the SR-1 spring brake valve located?
I think you mean QR-1 valve, and you're not guaranteed to have that. You could have a QR-1, QR-1, or an R14 relay valve. It's usually mounted high and near the center. Go under the truck, follow the lines from the emergency chamber of the brake chamber up - the valve they both connect to will be the metering valve for the spring brakes. A QR-1 valve will have three air lines attached to it, a QR-1C will have four, an R14 relay valve will have at least five.

How do you replace intake valves?
when replacing any valves i.e. exhaust or inlet the cylinder head must first be removed. this is quite a big job on most cars as it involves removal of timing belt/chain and stripping of cams. the valves themselves take around ten mins to remove, replace and grind in. to remove the valve the valve spring must first be compressed with either correct tool or i find a deep socket and hammer works fine. when this is done the collets that hold the valve will fall out of place and the valve can then be pulled out from the combustion side of the head. its also best to change the valve stem oil seal too when doing this. not sure what car it is but some vehicles require all valves on that side to be changed and use of specialist greases. to replace just push the new valve into the new seal and use grinding paste coarse first then fine to seat the valve in the head. now compress the spring (this time with correct tool) and with a screw driver position collets on stem. this is a major pain in the #### but a small screwdriver with grease on the end holds them mint. then release the spring and the valve should stay in place. best to check by lightly tapping spring to verify collets are corectly placed.

What is Valve pocketing?

What is the purpose of the spring keeper and washer?
the purpose of it is to connect the valve springs to the spring keeper to make a vale-springkeper it helps maintain the engine so it doesn't blow up and so the engine doesn't ignite

How do you remove valve springs?
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.
What is the right spring material quick release valve for steam application?
Spring loaded safety valve.
How do you know if your valve spring is brocken?
Your engine will probably missfire and you will not have compression in the cylinder that has the broken valve spring because your valve will stay open.
