The LPR- N Tester Valve is a full-opening, annulus pressure operated valve. It permits measuring multiple closed-in pressures in cased holes where pipe manipulation is restricted and a full opening string is required.
Features
*The ball valve operates independently of internal pressure changes, like with acidizing or fracturing operations, no need special bypass tools, but if a production packer is used, the pressure will transfer to formation directly if no bypass tool involved.
*Drastic temperature changes, like in acidizing operations, have little affect on the tool.
*Advanced materials and processes provide a unique metal-to metal seal for exceptional gas-holding capabilities.
*An open-in feature allows the operator to run the valve in the hole with the ball valve opened or closed
