Valve Overview

The lower kelly valve body is manufactured from 4145H modified fully heat treated alloy steel. This valve is a two piece design and is a positive opening, ball type valve. When installing the valve in the drill string, the same amount of torque should be applied in the make up of the valve as is used in making up tool joints.

By closing this valve before breaking a joint, you will save mud and keep the drilling floor cleaner and free of excess mud. The heavy duty body design enables the contractor to use this valve above and/or below the kelly.

The lower kelly valve comes complete with a hex-type operating wrench and pressed steel thread protectors.

Features and Benefits
  • Self-lubricating, ball-type valve

  • Stainless steel ball and non-corrosive seat are standard

  • Two piece design with fewer replacement parts for easy, economical repair
Maintenance

These lower kelly valves are designed for even the harshest drilling conditions; however, it is suggested that parts most subject to wear and tear be replaced regularly.
