This Ergonomically Improved Universal Valve Key Tool is used to open and close gate valves and ball valves within water and gas distribution systems. The valve key tool may be any length, made of strong material such as steel pipe. The valve key tool is manually operated, has no gas powered motor, but, enables the user to quickly and efficiently open and close valves. One hand stays stationary on the valve key stem while the other hand spins the handle around the stationary hand. There is an additional lever handle lower on the stem which allows initial leverage in order to get the valve moving. The moving arm of the user holds onto a spinning grip, thereby allowing ease of use and speed. The key end of the tool is formed such that mud and debris surrounding the valve will be displaced through vents at the top of the key.
