Upper & Lower Kelly Valves
(Kelly Cocks)

The Kelly Valve can be used as a dill pipe safety valve, Upper Kelly Valve, or Lower Kelly Valve.

As an Upper Kelly, the valve can be used to control blowout pressures by shutting off flow in the drill string at any time.

As a Lower Kelly, the valve can stop mud loss when the kelly is disconnected from the drill string.

Kelly Valves are manufactured from AISI 4140/4145 alloy steel and can be trimmed to standard or H2S. The Kelly Valves can be provided as one or two piece construction.

When ordering, please specify:

  1. Upper or Lower

  2. Tool OD

  3. Working Pressure: 5,000 / 10,000 / 15,000 PSI

  4. One piece or two piece construction

  5. Tool connection size (ex. NC-38)

  6. Standard or H2S Trim

  7. Bore

  8. Pressed or cast steel thread protectors
