The UZD 04 and UZS 04 block blowout preventer (double and single configuration) should be utilized when workover rig substructures have restricted height limitations. Combining units of the UZD 02 double ram or the UZS 01 single ram preventer and the UZ 03 annular blowout preventer into one single body make the block blowout preventer an ideal design for applications requiring low height restrictions.

The block blowout preventer requires no special spare parts and changes to any existing ram or annular packing style.
