POSITIVE CHOKE VALVE
Positive choke valve is used as flow control of wellhead and X-mas tree. All pressure-containing parts are made of alloy steel with enough tensile strength to ensure the safety and reliability at rated working pressure. Choke beans are made of hard alloys for good wear and erosion resistance.
Technical parameters:
- Pressure rating: 2000~15000psi
- Operating temperature: P U
- Operating medium: oil, gas and water
- Choke bore diameter: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16mm

ORIFACE CHOKE VALVE
Orifice choke valve is molded of two pieces of special carbon tungsten plates with excellent 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.
The valve is used for manifold such as drilling, fracture, mud circuit, ground high-pressure gas injection/production, it has a outstanding feature that the pressure difference between inlet and outlet, as closing, can press both of the plates fast together so as to put into effect of sealing cutting, especially in the case that the pressure suddenly rises or falls, the pre-set sign-rate of high/low pressure sensor can be helpful for automatic closing/shut so as to avoid heavy accident. It is outstanding advantage that it has long working life and ability of erosion/corrosion resistance in comparing with other choke valves.
