Choke Manifold

Choke Manifold

Choke Manifold is adopted to execute new drilling-well’s technique of balance pressure. Choke Manifold can avoid pollution of oil-layer and improve the speed of drilling and control blowout effectively. The choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components. TOT supplies various choke manifold from 2-1/16″~4-1/16″, with working pressure 2,000PSI~20,000PSI as per API SPEC 161C /6A.
