The Caledyne Torus valve is a fail safe closed Insert Safety Valve, which offers a permanent conduit through the centre of the valve. The valve is installed in the safety valve nipple profile and operated by the existing hydraulic control line.
The valve utilises a sliding sleeve mechanism to shut in production operated via a power spring and piston arrangement, akin to industry standard flapper type safety valves.
The lower sub can be configured to fit capillary tube, fibre optic or electrical penetrators or rotary seals for insert PCPs applications, where there is a requirement for a safety barrier.
Design optimised to reduce part count and complexity.
Minimal number of pressure seals and hence potential leak paths.
Modular design allows the same basic valve to be configured to accept the particular penetrator for the application.
Installed as per industry standard wire line insert safety valves.
Easily installed on coil tubing for hanger applications, such as insert ESPs.
Wells that require safety valves installed in combination with the following:
- Capillary tube installations.
- Velocity string terminated at the hanger.
- Insert Gas lift.
- Foam or chemical injection.
- Insert PCP completion.
- Insert ESP completion.
- Retrofit permanent monitoring, either electrical or fibre optic.
The Caledyne Torus valve main body is independently tested to API 14A. For further details of our test programme please contact your nearest Caledyne representative.
