9-Valve Choke Manifold

9-Valve Choke Manifold

9-Valve Plug Choke Manifold is a special type of oilfield manifolds designed to control flow, reduce pressure for upstream flowback and production equipment. Plug Choke Manifold consists of several plug valves, choke valves, high-pressure fittings, and pressure gauge. Skid of Plug Choke Manifold is manufactured from carbon steel with lifting lugs for convenient transportation and oilfield operation. Plug Choke Manifolds are also available as 5-Valve structure, but 9-Valve Choke Manifold allow operator to provide maintenance much easier because of additional two valves in each parallel lines. 


Rein Wellhead Equipment designs and supplies 9-Valve Plug Choke Manifold is designed to handle high-pressure, and to work under harsh working environment. Rein Wellhead Equipment is a supplier and manufacturer of Plug Choke Manifold in China.
