A frac system including a frac tree. The frac tree includes a frac head. The frac head defines a first inlet, a second inlet, and an outlet. The frac head receives frac fluid through the first inlet and directs the frac fluid to the outlet fluidly coupled to a wellhead. A valve couples to the second inlet of the frac head. A flapper valve is within the frac head. The flapper valve moves between an open position and a closed position to control fluid flow to the valve through the second inlet. The flapper valve aligns with a first axis of the outlet and the second inlet in the closed position and aligns with a second axis of the first inlet in the open position.
