Effective for use as a barrier for snubbing operations

The Single MagnumDisk Barrier Valve is designed for conditions up to 400°F and 15K psi, and is primarily used as a barrier for snubbing operations. Once the tubing is landed, the pressure is applied down the tubing to create the required overbalance to remove the MagnumDisk internal barrier device. The Single MagnumDisk Barrier Valve is also used in conjunction with completion packer BHAs and TCP BHAs as an underbalance device. In these applications, the MagnumDisk internal barrier device is removed by applying pressure from the surface with a MagnumDisk Drop Bar™ or a MagnumDisk Breaker Tool with slickline or coiled tubing.
