API 6A Cameron Manual Adjustable Choke Valve/Cage Type Choke Valve/ Orifice Type Choke valve
Choke Valve consists of needle type adjustable choke valve, positive choke valve, barrel type choke valve, cage type choke valve and orifice type choke valve, mainly used in onshore and offshore oil drilling and exploitation. The design and quality control conform to international standards. Bodies are made of premium low alloy steel, processed with advanced technology in conformance with API 6A 20th edition and NACE MR-0175.
*Needle Type Choke Valve
Mainly used on wellhead Christmas trees
Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion.
Open indicator and safe lock relief device.
Available with pressure relief valve.
Needle type choke valve and positive choke valve are interchangeable in body of the same size.
*Barrel Type Choke Valve
Used on choke and killing manifold to control casing pressure during drilling operation.
Easy flow adjustment, allowing stable flow.
Stem seal is made of special materials, delivering good chemical stability and corrosion resistance.
Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion.
Barrel-shape gate, annular gap between gate and seat with entry and outlet connecting all the time, mainly used on choke manifold or other high pressure lines
*Orifice Type Choke Valve
Mainly applicable to drilling, fracturing, slurry circulation and land high pressure gas injection/production. During shutoff, the pressure differential between entry and outlet pushes two orifices tightly against each other for seal and cutoff.
In case of abrupt pressure change, the valve can automatically shut off by pre-set high and low pressure sensor.
Equipped with upper and lower orifices. The orifice open extent can control flow by turning the handwheel. Orifice adopts hard alloy to increase erosion and corrosion resistance. The valve can be used as a shutdown valve.
Allowing a smooth choke flow curve.
Inner bore of the outlet features extended wear bushing to extend service life.
Tubing head adapter on the outlet can be replaced depending on different pressure conditions.
Stem seal is made of special materials to deliver good chemical stability and corrosion resistance to medium.
*Cage Type Choke Valve
The cage type design enables fluid flowing along the cage centerline, avoiding erosion and corrosion to choke components and reducing noise.
Choke components adopt hard alloy tungsten carbide to deliver wide choking area, low noise and excellent resistance to erosion.
Metal-to-metal seal, easy maintenance
Annular space helps to reduce corrosion to body.
Low open/close torque, stable operation
Easy flow adjustment, allowing stable flow curve.
Stem seal is made of special materials to deliver good chemical stability and corrosion resistance to medium
Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion.
