Abstract: Example aspects of an equalization valve are disclosed. The equalization valve can comprise a gate defining a first face, a second face, and a sidewall extending between the first face and second face, the gate further defining an equalization chamber extending into the sidewall, a first equalization channel extending from the first face to the equalization chamber, and a second equalization channel extending from the second face to the equalization chamber; and an actuation stem defining a lower portion slidably engaged with the equalization chamber, the actuation stem movable between a first position, wherein the actuation stem blocks the first equalization channel to prevent the flow of one of gas and fluid through the equalization valve, and a second position, wherein the actuation stem unblocks the first equalization channel to allow the flow of the one of gas and fluid through the equalization valve.
