Chock and kill mainfolds are important well control equipments in balancing pressure in near – balanced drilling wells during petroleum exploration. Choke manifold controls the casing pressure and maintains the balance inside the well, the soft closing of the well is realized by relieving pressure and maintains the balance inside the well, the soft closing of the well is realized by relieving pressure through the choke valve, through which the casing pressure can directly blow out in order to protect the well. Various kinds of valves are made of high – quality materials. The valve torpue of switch is small. It has good sealing, safe and reliable and products meet the standards requesting of API Spec and 16C. There are three pressure grades for the manifold made in our company: 35MPa/70MPa/105MPa.
