MBV By-Pass Valve

pennoiltools

Description

The MBV By-Pass Valve is a rotational, sleeve type circulating valve designed for use with Selective Stimulation Tools. This valve provides communication between the tubing and the casing annulus.

The MBV By-Pass Valve is used to bypass tubing fluid when running or retrieving downhole tools, such as the SST Cup Type Treating Assembly or the Model PJ Straddle Packer Assembly and if required can also be used for the circulation of fluids, or to relieve differential pressure between annulus and tubing.

The MBV By-Pass Valve features a pressure balanced sleeve design which allows for easy operation of the valve under high differential pressures. Specially designed chemical and wear resistant seals ensure reliable and trouble free operation. Exclusive to this valve are the thrust bearings which allow for easy operation under tension or compression loads.

Operation

The MBV By-Pass Valve is opened by rotating 3 turns to the right and closed by rotating 3 turns to the left at the valve. A tool with enough friction to hold the bypass valve in place must be run below to enable the bypass valve to function properly.

NOTE: It is good practice to run and pull tool strings with the valve in the open position to reduce swabbing and to aid in bypass.
