Hydraulic Open And Close Bonnets Blowout Preventer Control System Bottom Flanged
Introduction of Blowout Preventer Control System
Hydraulically or manually operated locking mechanism.
Includes secondary seal.
Offers flat and side door structures or hydraulic control type flat door structures.
The side door and shell are connected through triple hinges.
To open and close the valve in sequence, use the pressure bar (C type ram BOP).
The guide frame is positioned at the end of the side door. Upon opening the door, the ram can be pulled along the guide rail and replaced, specifically the D type ram BOP Pistons indicator. Upon opening the door, the ram can be pulled along the guide rail and replaced, specifically the D type ram BOP Pistons indicator.
Upon opening the door, the ram can be pulled along the guide rail and replaced, specifically the D type ram BOP Pistons indicator.
An oilway is intentionally concealed.
The ram cavity's shape is elliptical.
