Product Description

Kelly cock valve

 

Kelly cock is also called kelly Cock or drill pipe safety valve.

It is a manual control valve in the drilling string circulation system, which is one of the effective tools to prevent blowout.

Kelly cock valves are divided into upper kelly cock valves and lower kelly cock valves.

The upper kelly cock valve is used between the lower end of the faucet connector and the kelly.

The lower kelly cock valve is used between the lower end of the kelly and the upper end of the kelly.

It can be switched by turning 90° according to the instructions with a special wrench.

In the drilling operation, in order to avoid the occurrence of malignant accidents, the kelly cock valve should be installed on the upper and lower ends of the kelly to prevent the loss of drilling fluid and blowout prevention.
