it was invented by a man called Justin Andrews . valva lag- inlet valve closes after B.D.C -exhaust valve closes after T.D.C
the amount of valve open after T.D.C and B.D.C.
The purpose of the valve spring is to maintain contact between the components in the valve train, so the valve motion will follow the cam profile.

To move the valve down as the camshaft rotates.
The purpose of Valve Ports is to let exhaust gases out of the cylinder and to let air and fuel mixture into the cylinder!
The purpose of a pressure relief valve in a geyser is to release the pressure created inside due to evaporation of water.
A PVC Valve shuts off water A pcv valve is for positive crankcase ventilation in an engine
To regulate the pressure to a pre-determined amount.
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve
If you mean the ERG valve which relates to emission, I recommend having a mechanic do it, but the valve itself is not expensive about $50.00. I let this problem lag on and it blew a cap called a diverter valve that has something to do with vacuum, dont wait like I did.
it controls the pressure
