Brief: From concept to demonstration, this video highlights the evolution and practical outcomes of the Ball Activated Drop Ball Circulating Valve. You'll see how this coiled tubing pressure control equipment operates, learn the step-by-step process of activating the valve using a drop ball, and witness a demonstration of how pressure shears the pins to open circulation ports for enhanced flow control.

Custom sizes and specifications can be manufactured upon request to meet specific operational needs.
সাধারণ জিজ্ঞাস্য:
How is the Ball Activated Circulation Valve activated?
The valve is activated by pumping a correctly sized drop ball through the coiled tubing string. The ball seats in the valve, blocking flow. When pressure is increased, the shear screws holding the seat shear, shifting it downward to uncover the circulating ports.
What are the key specifications available for this circulation valve?
Key specifications vary by size and include OD, ID, connection type, maximum shear pressure of 5000 psi, temperature rating of 0-400°F, tensile strength (e.g., up to 165,000 lbs for the 3 1/8" size), and corresponding drop ball sizes such as 5/8" or 1 1/8".
Can the shear pressure for activating the valve be adjusted?
Yes, the shear pressure required to activate the valve can be adjusted on the surface by varying the number and type of shear pins used in the assembly, allowing for customization based on operational requirements.
