Wellhead Equipment: Sucker Rod and Injection Valves

Sucker-rod pump fittings and injection valves are intended to seal the wellhead, to suspend downhole pipelines, to control and monitor the flow of the medium.

To eliminate the need for external piping between the annulus and the discharge line, a bypass device is provided in the body of the tubing head.

Moreover,

• Sucker-rod pump fittings can be equipped with a wellhead packing to compensate for any misalignment of the sucker-rod pump rod that occurs during operation;
• Injection valves can be equipped with:
  • a ball valve or cutoff valve with replaceable throttles;
  • media separators for installing and protecting the pressure gauges from unfreezing.
