    Kelly Valve

    Product Detail

      Kelly Valve 1430355447759037.jpg

      Kelly valve is a manually operated ball type drill stem valve; it is divided into upper Kelly valve and lower Kelly valve. The upper Kelly valve is connected between lower end of swivel and upper end of Kelly; the lower Kelly valve is connected between upper end of drill pipe and lower end of Kelly or connected between lower end of Kelly saver subs. The Kelly valve can be opened on or closed off by only turning the special operating wrench at 90° according to indicating direction. During drilling operation, the Kelly valve shall be connected at upper end and lower end of Kelly.
      The sealing principle for Kelly valve is that the ball is positioned and provided with proceeding stress by the lower seat supported by spring load and a close seal between ball and ball seat is provided. During normal drilling operation, the hole is kept unblocked by turning the stem to be “on” position; In case of kick or blowout, turn the operating stem to be “off” position to close off the internal bore of drill string, the kick or blowout accident is avoided due to a high pressure sealing situation between ball and ball seat.
      When ordering please specify:
      ● Upper or Lower type;

      ● Tool OD;
      ● Working Pressure: 5,000 / 10,000 / 15,000 PSI;
      ● Tool connection.

      Full Opening Safety Valve 1430357797133673.jpg

      Full Opening Safety Valve (short for FOSV) is a ball type safety valve used to stop flow through the drill string when the drill string is being withdrawn from the well.
      TIANHE FOSV is dual body full-opening safety valve, so it does not interfere with the running of tools such as core barrels or survey instruments. It is designed to be stabbed into the top joint of drill pipe or tubing string at the rig floor and closed quickly in case a well kicks.
      The ball-type design permits the valve to be compact, easy to handle, and yet have great strength. Standard test pressure is 10,000PSI, but higher pressure ratings are available.
      FOSV and operating wrench be should be maintained on the rig floor at all times.
      When ordering please specify:
      Connection.
