MOV Chokes With four trim designs, a range of choke sizes, and expertise in materials, Cameron has the technologies, experience, and knowledge to help operators increase flow control efficiency while decreasing production costs. Materials Our commitment to materials research enables technologies that control the effects of cavitation, erosion, nd freezing—three of the greatest a threats to flow control. This research provides an extensive database from which the proper materials and alloys can be selected for specific choke applications. In addition to testing chokes over a wide range of pressures,...

Styles Our MOV chokes are classified into four basic styles depending upon the kind of service needed: 1. Style 0—Standard service Standard service valves are the most costefficient choke styles. They generally are intended for sweet crude oil, deaerated water, sweet natural gas, and other noncorrosive fluids. 2. Style 8—Sour service In addition to the requirements of the standard valve type, the materials of the pressure-containing parts of this style meet the requirements of NACE MR0175. Sour service chokes are intended for applications with H2S present as defined by NACE MR0175 requirements....

Multiple Orifice Valves—Multiple Solutions Operation and features For more than six decades, the Cameron MOV choke has set the standard for precision flow control in a wide variety of applications all over the world. As one of the Cameron four main choke technologies—which includes needle and seat chokes, control chokes, and multistage chokes—the MOV choke is recognized for its proven durability and precise flow control. 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...

Multiple Orifice Valves—Multiple Solutions Applications The Cameron MOV line covers 1- to 6-in [25- to 152-mm] sizes that can handle pressures up to 10,000 psi while operating at temperatures ranging from −50 to 650 degF [−46 to 343 degC]. They are manufactured to meet API, ANSI, and NACE standards. MOVs are available in both adjustable and positive configurations as well as angled and inline body configurations, with a variety of end connections to meet most requirements. The near-linear flow characteristics of the MOV make it well suited for production choke applications, including ■■ wellhead—attaches...

Actuation The actuation of MOVs can take many forms, including ■■ handwheel gear operator linear, hydraulic, electric, or stepping actuator. Any MOV can be actuated, and field conversion from manual to actuated is possible on most models. Pneumatic actuators Pneumatic actuators are applicable to all Cameron MOV choke models. They are especially effective for economical, automated control of the M2 and larger choke valves. Accessories such as positioners, limit switches, filter regulators, local pressure controllers, solenoid valves, and more are available with pneumatic actuators. Selecting the...

Stepping actuators The S-15000 stepping actuator is designed to open, close, or open and close MOV chokes in precise 1° increments. The capabilities of this heavy-duty actuator make it particularly applicable to M3, M3G, M4, and M6 MOV chokes. The S-15000 draws its name from the amount of torque it delivers— 15,000 in.lbf—and is designed to work with either 100-psi pneumatic or 1,000- to 3,000-psi hydraulic fluid supply. The proven design features of the S-15000 make it ideal for remote and automated control for locations on land, offshore, or subsea. The S-15000 operates at temperatures from...

The MC10 choke is a 1-in [25-mm] nominal inline MOV choke and is suitable for a wide variety of applications. It is commonly used in water and gas injection operations as part of enhanced recovery processes. The MC10 choke's precise control has gained acceptance in gas injection and gas lift operations and production systems. The trim design resists freezing in CO2 service. It also has positive shutoff and adapts easily to field applications using electric, hydraulic, and pneumatic actuators. The standard MC10 choke end connections are 1-in [25-mm] and 2-in [51-mm] female threaded interfaces...

The MC20 choke is a 2-in [51-mm] nominal inline MOV choke with suitability for multiple applications, particularly water and gas injection operations to achieve EOR. The MC20 choke's precise control also has gained acceptance in gas injection and gas lift operations and production systems. The trim design resists freezing in CO2 service. It also has positive shutoff and easily adapts to field applications using electric, hydraulic, and pneumatic actuators. The MC20 choke is available with 2-in [51-mm] female threaded interfaces or 2- to 4-in [51- to 102-mm] flanges. Other interface options are...

Like the MC10 choke, the M1A has the same economical, easy-to-replace trim. The M1A choke is available with 1-in [25-mm] and 2-in [51-mm] male-threaded, 2-in [51-mm] male-threaded, 2-in [51-mm] flanged or butt-weld (BW) configurations. Other end connections are available as required. Optional tungsten carbide or Stellite outlet wear sleeves are available on the M1A choke for erosive or cavitation conditions. The M1A choke is designed for easy automation. You can change from manual to actuated right in the field. No additional brackets or adjustments are required for most models. Maximum Body...
