Abstract: 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.

Abstract: A sleeve assembly has a sleeve axially moveable within a housing, the sleeve being positively locatable within a wellbore for reliable axial shifting of the sleeve between an uphole position and a downhole position. Stops and shoulders, which delimit the shifting of the sleeve between open and closed positions, are located in an annulus between the sleeve and the housing. Uphole and downhole ends of the sleeve and the housing have opposing ramps formed thereon. Locating shifting tools run through the sleeve assembly are engageable only in a locating profile in the sleeve and cannot engage in the annular stops or in gaps formed in the bore, uphole and downhole of the sleeve, as the ramps act to guide the locating tool therethrough. As the uphole and downhole sleeve ramps converge toward either of the uphole or downhole housing ramps during shifting thereof, debris is diverted into the bore allowing the sleeve to shift fully uphole or downhole.
