Milling Circulation Valve
The DTI Milling Circulation Valve provides a constant fluid flow path to the motor or BHA during milling operations, whilst also providing a means of high volume circulation to the annulus whenever required.
Designed to be run above a motor, the DTI Milling Circulation Valve enables unlimited switching between milling operations and high flow rate clean out. This increases the flow rate available to effectively remove debris from the well and prevents motor damage during hole cleanout.
The DTI Milling Circulation Valve is activated by picking up o bottom and briefly overpressuring the toolstring to release a hydraulic lock. Closing the Milling Circulation Valve is acheived simply by reducing the flow rate to normal milling rates and sitting back down.
- Mechanism is locked during milling to ensure constant fluid flow to the motor
- Adjustable hydraulic lock opens valve at desired overpressure
- Large flow area allows very high circulation rates for effective hole cleanout
- Valve closes easily by setting down weight
- Robust dynamic seals and high performance treatments prolong the life of the valve
DTI offer alternate sizes, materials and thread connections. Please contact us for more information.
