Əsas texniki xüsusiyyətlər

Choke Valve Types: Needle type adjustable choke valve , positive choke valve , barrel type

choke valve cage type choke valve and orifice type choke valve


Ərizə: 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.


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

müqavimət.

● 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

təzyiq sensoru.

● 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

şərtlər.

● 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.
