Product Description
High Pressure Slim Hole LPR-N Valve Overview
The 3 7/8" LPR-N Valve is a full-opening tester valve specifically designed for slim hole drill stem testing operations. This annulus pressure-operated valve enables multiple closed-in pressure measurements in applications where pipe manipulation is restricted and a full-opening string is required.
Operating Principle
The LPR-N Tester Valve features a ball valve mechanism controlled by a power section with a moving piston. One side of the piston is exposed to hydrostatic pressure while the other side interfaces with pressurized nitrogen. During operation, annulus pressure application moves the piston downward to open the ball valve, while pressure release allows nitrogen pressure to return the piston upward, closing the valve.
