Kelly Valves

Our Hartmann Kelly Valve enables a safe drilling and production operation.

Kelly Valves

Our Hartmann Kelly Valves are manufactured and tested to API specification 7-1 and in compliance with IS0 9001:2015.

Kelly valves are used as a safety valve in drilling rigs. The use of the kelly valve enables an interruption of the flow inside the drill string. Depending on the conditions, we supply our kelly valves with different overall lengths, external and internal diameters as well as thread types. Manufacturing is done according to API specifications 7-1 and in compliance with IS0 9001:2015. Certification (Type Approval) by ABS and DNV is possible.
