  • Frac valve with ported sleeve
    Patent number: 9051810
    Abstract: Frac valves used in completing oil and gas wells are provided. The valves comprise a cylindrical housing adapted for assembly into a liner for a well. The valve housing defines a conduit for the passage of fluids through the housing. Preferably the conduit has a substantially uniform diameter. The housing has a port which can allow fluids to pass from the conduit to the exterior of the valve. The port may be shut off or left open by a valve body mounted on the housing. Preferably, the valve body is mounted between inner and outer walls provided in the housing. An actuator is provided to move the valve body between its open and closed positions. It comprises a receiver that is adapted to receive an activation signal. Thus, the valve may be actuated by introducing a transmitter into the housing conduit which transmits an activation signal.
