OMNI Circulating Valve

the OMNICIrculatingValve is an annulus pressure operated, recloseable circulating valve. Throughout the operation, the tool is repeatedly cycled up to a predetermined annulus pressure and then released.

the operating and control mechanisms are contained in a closed oil system activated by annulus pressure acting on the nitrogen chamber, allowing an unlimited number of pressure cycles.

the circulating valve and the ball valve work together to keep circulating pressure off the formation. The ball valve will close before the circulating valve opens. The ball valve closes off the workstring.





1) Permits well testing, pressure testing, and fluid circulation

2) Allows unlimited number of pressure cycles

 1) Other sizes available on request.

2) Meets requirements of NACE-0175 (>175°F)

3) the values of tensIle, burst, and collapse strength are calculated with new tool conditions.

4) Pressure rating is the differential pressure at the tool. (Differential pressure is the difference in pressure between the casing annulus and the tool ID.)
