Product Description

 

Choke Valve--Positive /Orifice choke valve

Positive choke valve
Brief introduction:
  The positive choke valve is used to be matched with X' mas tree or wellhead assembly. which is applicable for flow-rate adjustment,that is,to replace the choke is help for alternation of flow-way cross- - area and flow-rate control.
 

Main technological parameters:
Rated pressure: 2000- 1 5000psi
Working temperature: PU
Working medium: petroleum & natural gas.
Choke bore: φ3 thru φ12



Structural feature:
All pressing parts are made of alloy steel and have enough tensile strength, that ensures the valve safe and reliable at rated working pressure .
Choke is made of carbide with fine grind & erosion resistance properties .

Orifice choke valve
Brief introduction:
Orifice choke valve is molded of two pieces of special carbon tungsten plates with rather ability of erosion resistance. one of which rotates to alter the concentricity between the upper orifice and lower orifice of two plates so as to adjust the flow-rate of fluid or gas.



Application:The valve is used for manifold such as drilling ,fracture,mud circuit,ground high--pressure gas injection/production.



Advantages:It has long working life and ability of erosion/ corrosion resistance in comparing with other choke valves.
