(6) adjustable throttle valve

1. Valve stem and spool are made of hard alloy;

2, with wear resistance, erosion resistance and reliable performance;

3, suitable for oil production wellhead equipment;

4, working pressure: 2000 ~ 15000Psi;

5, nominal diameter: 2-1/16″ ~ 4-1/16″.

(7) fixed throttle valve

1. Throttle nozzle material is made of ceramic nozzle or hard alloy;

2, with wear resistance, erosion resistance and reliable performance;

3, suitable for oil production wellhead equipment;

4, working pressure: 2000 ~ 15000Psi;

(8) external sliding sleeve type throttle valve

1. Valve stem and spool are made of hard alloy; With wear resistance, erosion resistance and reliable performance;

2, switching torque is small, can close the fluid, small noise;

3, suitable for oil production wellhead equipment

4. Working pressure: 2000~20000 psi

5, nominal diameter: 2-1/16″ ~ 4-1/16″

(9) butterfly valve

1, butterfly valve simple structure, small size, light weight, only by a few parts.

2, just rotate 90° can be quickly opened and closed, simple operation.

3, fully open, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the resistance generated by the oil valve is small, so it has better flow control characteristics, can be used for regulation.

(10) forced single flow valve

1, the working medium one-way flow;

2, often used in killing manifold;

3. Working pressure: 2000 ~ 15000Psi;

4, nominal diameter: 2-1/16″ ~ 4-1/16″.

(11) rotary single flow valve

1, the working medium one-way flow, metal seal;

2. Working pressure: 2000PSI ~ 15000PSI;

3, nominal diameter: 2-1/16 “~ 7-1/16”.

(12) Ball valve

1, the valve seat floating, so that the ball and valve seat between the fit more perfect;

2, sealing more reliable;

3, fixed ball structure, small switching torque;

  • Small flow resistance, no resistance when fully opened.

(13) Cock valve

1, the cock oil valve can be divided into steam, manual dual-use, with a limit device, switch freely, the end can be connected by nona or LP thread connection, can replace the cementing, fracturing equipment SPM company of the same type of products.

2, precision machining of the plug after coating anti-corrosion performance is excellent, the working pressure range of 40-105 MPa.

(14) Mud valve

1. The spool is vulcanized by corrosion-resistant rubber; Corrosion and reliable performance;
