Product Explanation:Kelly Valve also named Kelly Cock/Drill Pipe Safety Valve allowing free passage of drilling fluid without pressure loss. The valve can be used as a dill pipe safety valve or upper Kelly valve to control blowout pressures, or as a lower Kelly Valve to prevent loss of drilling fluid when the Kelly is disconnected. It has a pressure rating of 5,000psi or 10,000psi or 15,000psi.
Upper Kelly Cock Functionality: The upper Kelly cock valve is installed above the Kelly to provide a barrier when backflow or kick is detected. By closing the valve, the operator can quickly isolate the drill pipe from the surface equipment, minimizing the risk of blowout.
Lower Kelly Cock Functionality: The lower Kelly cock valve is installed below the Kelly to act as a secondary shut-off point in the event the Kelly is removed. This valve is crucial in providing additional protection against backflow and blowouts in high-pressure environments.
Safety and Reliability: Both the upper and lower Kelly cock valves are engineered to handle high-pressure environments, ensuring they are dependable in emergency situations. Built with metal-to-metal seals and optional elastomeric seals, these valves provide a tight seal under the most extreme conditions.
Easy Operation: These valves are manually operated with a lever for easy and fast engagement. In emergencies, operators can quickly shut off fluid flow to avoid critical incidents like blowouts or excessive pressure buildup.
Durability: Made from high-strength materials such as carbon steel and alloy steel, these Kelly cock valves are designed to withstand the most challenging downhole conditions, including corrosive fluids and abrasive materials. The tungsten carbide hardfacing option increases resistance to wear and tear, extending the service life of the valve.
