Choke manifold is the necessary equipment for controlling well kick and implementing oil and gas well pressure control technologies. Killing operation is done by choking function of the choke valve and which can control well head casing pressure and stand pipe pressure while replacing the contaminated drilling fluid, so as to recover pressure control of the drilling fluid column on bottom hole and stop any overflow. By way of pressure release function of the choke valve, wellhead pressure can be decreased and Soft Close of the well is realized. Wellhead casing pressure is reduced through large release of the blow out preventing valve to protect the wellhead BOP. The product is designed and produced based on API Spec 16C 6A, and all valves are made of erosion materials in order to have good seal and high reliability.
