Internal Pressure-Operated (IPO) Circulating Valve

the Internal Pressure-Operated (IPO) Circulating Valve is a single-shot circulating valve which allows circulation through the workstring before trip-out and serves as a drain valve during trip-out. It can be run in cased holes or openholes and maintains a full bore through the tool.

the IPO Circulating Valve is used in the following situations:

When a full-opening string is needed

When redundant backup to annulus pressure-operated circulating valves is needed

When a limited amount of annulus pump pressure is available to operate annulus pressure tools 





1) Requires no string manipulation to operate tool

2) Permits passage of wireline tools through full-opening bore

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.)
