Model FZ Ram BOP
Ram chutes are formed on preventer body to timely discharge the accumulated sand for ensuring flexible opening and closing of rams. Besides, the ram can center by itself (by its own guide block).
Exposed locking screws are used on the cylinder piston to enable operator to visually inspect the actual position of the rams.
Two or four flanged/studded outlets (Ø52-Ø103mm) are designed according to the customers' needs.
Various pipe rams and blind rams are available if required.
Connections are flanged/studded |
