Why does the giraffe need special valves in the blood vessels that can close when it is getting a drink?

The blood pressure in the giraffe's body is very high so that blood pumps to the head but when it lowers the head to drink the pressure would be extreme and it would die with out the valves.

What is Common Types of Valves?
There are a few different designs: Parallel disk gate valves use two disks with a spring in between them, sliding into the seats. At low pressure, the spring forces the disks outward against the seats, sealing off the valve. At high pressure, all the sealing is accomplished by the downstream disk. Wedge gate valves use a tapered disk that slides into two seats set at a slight, converging angle. The wedging action provides the sealing force between the disk and the seat. Single disk gate valves are used where the flow is always one way (like sluices on dams). There is some flexibility in the attachment of the disk to the stem, so the differential pressure on the disk pushes it against the seat, sealing it off.
