Adjustable choke & Positive choke valves are often used in the oilfield when drilling, testing, production our adjustable choke valve is designed and manufactured in accordance with API 6A and API 16C standard and improved from customer feedback. They are easy for operation and simple to maintain.
Manufactured and tested in accordance with API 6A.
Flow adjustment is indicated on a measuring scale.
Maximized valve service life.
Carbide alloy is embedded into stem needle of valve, seat.
The stem packing is a re-energize while the valve in under pressure.
Critical application from 2000 psi to 15000 psi pressure.
Seat and valve needle of API 6A Choke valve made by hard alloy, which improves the corrosion resistance, flushing resistance performance.
API 6A Choke valve is Small impaction and nosie of fluid.
The stem is self locking energizing seal, API 6A Choke valve is reliable sealing performance.
1) Material of throttle nozzle made of ceramics or hard alloy.
2) Controlling the flow rate by replacing the throttle nozzle of different sizes.
1) The torque of Cage type choke valve is small torque, it can both adjust and cut off the fluid etc.
2) Barrel type, wedge type and orifice type are mainly applied for choke manifold.
1) Needle type chock valve is mainly applied for Christmas tree assembly.
