Choke and Kill Manifolds
From noncorrosive to extreme sour oil and gas
Manage well pressure fluctuations encountered during drilling.
The term “multiple orifice” refers to the exclusive design of the MOV, which uses a set of adjacent discs, each containing a pair of circular openings or orifices. Other shapes can be used for custom applications.
The two discs are diamond lapped on the mating surfaces to tolerances near two light bands of flatness. This allows for complete shutoff over a prolonged period and precise flow rate control throughout the service life of the equipment. In fact, most MOV chokes meet the requirements of ANSI B104 Class IV shutoff as standard.
The near-linear flow characteristics of the MOV make it ideal for production choke applications, including
