The features are as follows:
Not only the pipe rams and blind rams but also the variable bore ram and shear rams are available without any structure change.
Matched-manufacturing isn't necessary for the bonnets and body, so the discrepancy could be eliminated by the structure. And it's convenient for the maintenance in the future.
The outlets on the both sides of the body make the operation on site flexible.
Three kinds of locking system could be chosen: The internal manual locking system, the outside manual locking system and the automatic hydraulic system.
The pressurized self-sealing sealing mechanism is used between the body and bonnets, so it's not necessary to apply too much pretightening force to secure the reliability of sealing.
It's very convenient to lift and transport the BOPs with the four lifting rods.
The new sealing mechanism of ram shaft secures the sealing reliability under the high pressure
The ring grooves of flanges are all lined with the corrosion resistant alloy.
