Spec. 

Kelly cock also named Kelly valve, a manually operated ball valve run in the I. D of drill string, is one of effective tools for prevention from blowout. The Kelly cock is divided into upper Kelly cock valve and lower Kelly cock.

The Kelly valve seals in both directions with metal to metal seals, available in 5,000 psi (350Mpa)/10,000psi (70Mpa)/15,000psi (105Mpa) working pressure. 

The valves use a hexagon socket on the operating stem and have positive stops in the open and closed positions. The design of the body limits the plug rotation to 90.between the open and closed positions.
