API upper and lower Kelly Valves or Drill Pipe Safety Valve
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
Specifications
Kelly valve is a manually operated ball type drill stem valve; it is divided into upper Kelly valve and lower Kelly valve.
Kelly Valve features:
The sealing principle for Kelly valve is that the ball is positioned and provided with proceeding stress by the lower seat supported by spring load and a close seal between ball and ball seat is provided.
During normal drilling operation, the hole is kept unblocked by turning the stem to be “on” position; In case of kick or blowout, turn the operating stem to be “off” position to close off the internal bore of drill string, the kick or blowout accident is avoided due to a high pressure sealing situation between ball and ball seat.
When ordering please specify:
Upper or Lower type;
Tool OD;
Working Pressure: 5,000 / 10,000 / 15,000 PSI;
