Caledyne’s innovative “Torus” safety valve technology has now been granted a European patent. Developed at the company’s base in Aberdeen, Scotland, the Torus safety valve allows for a conduit through the valve without compromising the fail-safe close ability of the tool.As the conduit is independent of the production flow path, it may be electrical, hydraulic, fibre-optic, rotating or reciprocating.

David Martin, director of Caledyne and one of the inventors of the Torus safety valve said: “Torus is part of a system that lets the operator retrofit a completion string inside the existing completion without performing a workover. The Torus safety valve complements our PHI surface termination system.We describe these products as enabling technologies as they allow operators to install equipment that may have been uneconomic if performing a full workover.”
