Hartmann Valves launch a new standard in the field of Kelly Valves. As a drill string valve, Kelly Valves are used as a safety valve in the drilling rig. In the event of a possible kick they prevent the medium, by switching the ball to the closed position. The new developed Hartmann Kelly Valves are technically characterised by a wide temperature range from -46°C to +180°C (L/X), class 2 as standard and by their longevity and resistance to higher differential pressures.
After successful use in the Innova Rig drilling unit by long-term customer H. Anger’s Söhne Bohr- und Brunnenbaugesellschaft mbH the Hartmann Valves Kelly Valves were now officially included in the product portfolio. Manufactured and tested according to API specification 7-1 and in compliance with ISO 9001:2015 the Kelly Valves are available in different lengths, thread types and dimensions. The development of the Kelly Valve is based on decades of experience in the oil, gas and geothermal drilling industries and product know-how in the field of special ball valves and wellheads. Thanks to the investment in research and development and the expansion of the product range, Hartmann Valves now offers its customers an all-round package incl. short term delivery, stocking in Germany, spare parts and overhaul with the Kelly Valves.
Hartmann’s Kelly Valve expert Nora Greßies is available for any technical and sales related questions.
