Abstract: Fracturing systems with frac valves having gates for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a cavity transverse to a bore. A gate is positioned in the cavity and is movable between open and closed positions to selectively block flow through the bore. The gate includes a seal assembly positioned to seal against a sidewall of the cavity to surround the bore and block flow through the frac valve when the gate is in the closed position. The seal assembly can be actuated between a less-energized state and a more-energized state following movement of the gate within the cavity from the open position to the closed position. Additional systems, devices, and methods for fracturing are also disclosed.

Abstract: Fracturing systems having rams for controlling flow through fracturing trees are provided. In one embodiment, a fracturing system includes a frac stack mounted on a wellhead. The frac stack can include a flow control device having a housing and a single ram for opening and closing a bore of the housing. The single ram can form a seal with the housing around the bore without seats. Additional systems, devices, and methods for fracturing are also disclosed.

Abstract: A system that includes a wellhead. The wellhead defines a bore. A hanger system is positioned within the wellhead. The hanger system includes a piston angled relative to a longitudinal axis of the bore. A first spring biases the piston in a first direction. The piston contacts a slip segment to couple the slip segment to a casing string.
