Briefly Introduction  
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

Features and Benefits

• Requires no string manipulation to operate tool

• Permits passage of wireline tools through full-opening bore

OperationThe IPO circulating valve is operated by internal pressure (500 to 10,000 psi above hydrostatic). Pressure required to operate the tool is determined by shear pins, which hold the sliding valve in the closed position. To open the valve, tubing pressure is increased to a pressure above annulus hydrostatic equal to the shear value of the shear pins. Once operated, the IPO circulating valve is locked open.

Specifications:
1. Halliburton type, all could change with Halliburton parts.
2. All equipments are produced according to API standard NACE MRO175-2002

Below are specfor you reference:    

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

*Service temperature up to 450°F (dressed with 600 series O-rings and PEEK™ backup seals)

**The values of tensile, burst, and collapse strength are calculated with new tool conditions, Lame's formulas with Von-Mise's Distortion Energy Theory

for burst and collapse strength, and stress area calculations for tensile strength.

***Pressure rating is defined as the differential pressure at the tool. (Differential pressure is the difference in pressure between the casing annulus and

the tool ID.)

These ratings are guidelines only. For more information, consult your local Halliburton representative.
