Inside BOP Valves

M&M offers two variations of “dart type” inside blow-out preventers (IBOPs). The traditional style is two-piece and is similar in construction to other dart type IBOPs. Recognizing the need to reduce as many internal connections as possible we have also developed a one piece IBOP.

An IBOP is a “dart” type pressure sealing device that has a conical head which mates to a conical negative sealing surface. This design allows for one-way pressure containment.

One-Piece Inside Blow-Out Preventers

M&M’s One-Piece IBOP offers all the same functionality of a traditional two-piece design, but with the addition of several key benefits. A one-piece design allows the IBOP to be shorter in length while also creating the possibility for smaller outside diameters. The one piece design also eliminates the service break, which removes the need to torque a connection after assembly and allows for quicker disassembly, as there is no connection to break out. One-piece IBOPs also require less manufacturing time than two-piece, allowing for a faster lead time offering to the customer.

Our IBOPs can be designed and manufactured to meet any applicable industry standard.

Two-Piece Inside Blow-Out Preventers

M&M’s Two-Piece IBOP is our improved version of the long-time standard for dart valves in the industry. We make it our own by manufacturing our IBOPs out of superior materials and with our best in class engineering and attention to detail. That is why M&M IBOPs are well known in the industry as time tested and reliable performers.
