·Control pressure to prevent overflow and blowout.

·Reduce wellhead casing pressure by relief function of choke valve.

·Full-bore and two-way metal seal

·Choke bean features hard alloy inside, delivering high resistance to erosion and corrosion.

·The relief valve helps to reduce casing pressure and protect BOP.

·Configuration type: single-wing, double-wing, multiple-wing or riser manifold

·Control type: manual, hydraulic, RTU

Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas

well in the course of drilling, as it is, the device is adopted to execute new drilling-well's technique of balance pressure, which

can avoid pollution of oil-layer, improve the speed of drilling and control blowout effectively.

Kill Manifold consists of check valves, gate valves, pressure gauges and line pipes. One end of the kill manifold is connected to

drilling spool and the other to pump. Kill manifold is necessary equipment in well-control system to pump drilling fluid into well

barrel or inject the water into wellhead.
