Abstract:
A valve for preventing water hammer includes a speed reduction device for reducing a speed at which the valve may be closed. A method of preventing water hammer includes closing a valve at a fire hydrant after extracting water from the fire hydrant, in which the valve comprising a speed reduction device that increases an amount of time needed for closing the valve, and operating the valve to close the valve comprises operating the speed reduction device.

Claim (Index 6):
A method of operating the valve of  claim 1  for preventing a fluid hammer effect, the method comprising:\n connecting the valve to a fire hydrant; \n closing the valve at the fire hydrant after extracting water from said fire hydrant; \n wherein the valve comprising the speed reduction device that increases an amount of time needed for closing said valve, and operating said valve to close said valve comprises operating the speed reduction device such that said increased amount of time needed for closing said valve prevents an occurrence of fluid hammer associated with said closing of said valve; \n wherein the speed reduction device for reducing a speed at which said valve may be closed comprising the gear train has the gear ratio such that a number of rotations of said valve handle results in a lesser number of rotations of a screw that translates said gate with respect to said channel.
