Kelly valve also named Kelly cock or drill pipe safety valve. It is a hand control valve in drill string circulating system and it is one of the effective tools to prevent blowout. Kelly valve is divided into Upper Kelly Valve and Lower Kelly Valve. Upper Kelly Valve is connected between swivel sub and Kelly. Lower Kelly valve is connected between lower end of Kelly and top of drill pipe or lower end of Kelly save sub. Rotating the wrench of full opening safety valve 90° to realize on and off. In the drilling operation, in order to avoid malignant accidents, Kelly valves should be connected to both end of Kelly to prevent loss of drilling fluid and blowout.
Our Kelly valves are supplied with end connections for pressure test verification. When connections are machined, the corresponding bevel diameters specified for the connection on the joining product shall be used.
Galling of rotary shouldered connections and sealing shoulders occurs frequently in field usage. Treating the shoulders and threads with a coating of zinc or manganese phosphate has proven to be beneficial in lessening this problem. Therefore a treatment of zinc or manganese phosphate shall be applied to the threads and the sealing shoulders of all end connections of Kelly valves and other drill stem safety valves manufactured from standard steels. Application of treatment shall be after completion of all gauging.
We also produce H2S resistance Kelly valves, which adopt high quality imported sulfur-resistance material.
