A pressure control valve located in an improved tubing hanger of an oil or gas wellhead. The pressure valve having in-line communication with the production bore and having pressure activation. The pressure activation is imparted by utilizing hydraulic pressure input through the existing test port into the tubing head adapter void space. The pressure actuates the in-line wellhead control valve in a safer, more efficient, and less expensive manner than current industry practices and provides a barrier to pressurized hydrocarbons, both liquid and gas, produced by the well. The control valve eliminates the need for a lubricator and expensive specialized equipment. The valve is easily operated by a standard hydraulic hand pump through the existing test port of the tubing head adapter, and fits inside the tubing hanger.
A method of sealing a well bore production tubing string at a well tubing head using a test-port pressure actuated sealing apparatus installed in-line with the well bole production tubing string.
The method of claim wherein the sealing valve further comprises a seal body with a radial cross section to engage the well bore production tubing string.
The flow body of claim 17 being sized to fit and align with the well bore production tubing string.
The flow body of claim 18 formed to interface with the sealing valve.
The seal body assembly of claim 20 further comprising a workpiece to bias the sealing valve to a closed position.
