KINGWELL  RD Circulating Valve Drawing

For 5" RD Circulating Valve
The RD Safety Circulating Valve is a full opening, annulus pressure operated single shot safety circulating valve used in cased hole operations. It is mainly used to seal oil-gas layer when the formation test ends and carry on cycle operation. As a “safety valve” the tool can be operated at any point during the test to close off the work string and isolate the formation.
