Detailed Description

The manufacturer has applied the same stringent testing used on its maximum reliability tubing-retrievable safety valves (TRSV) to its BigBore™ wireline-retrievable safety valve (WLRSV). This valve offers the durability and reliability of TRSVs through metal-to-metal (MTM) sealing of the contoured flapper, enhanced body connections, and debris isolation. The contoured flapper provides a large ID compared to other valve designs, while providing enhanced flapper sealing. Another significant feature of this valve is its ease of on-location servicing. The construction of the upper end of the valve provides for easy access to the valve’s external packing. Once the lock is removed, the packing retainer sleeve can be removed and serviced. The savings made possible by an enlarged ID, enhanced performance, and ease of service have made it an excellent choice for replacing equipment currently installed in existing completions.
