1. A fracturing apparatus comprising:
a frac valve to control flow of fracturing fluid through the frac valve, the frac valve comprising:
a housing having a bore to convey the fracturing fluid, wherein the bore has a central axis extending from an inlet of the housing to an outlet of the housing;
a seal disposed within the bore; and
an actuator coupled to control movement of the seal, wherein the actuator is disposed within the bore so as to move the seal between a closed position in which the seal blocks fracturing fluid flow through the bore and an open position that allows fracturing fluid flow through the bore, the actuator includes flow-by conduits that permit fracturing fluid flow past the actuator when the seal is in the open position, and the actuator is positioned inline with the inlet of the housing and the outlet of the housing such that the central axis extending from the inlet of the housing to the outlet of the housing intersects the actuator.
