Throttle valve is damaged by the erosion capacity of the two plates very special molded tungsten carbide materials. Through the rotation of one plate to change the hole and the next two holes on the plate between the concentric in order to achieve the regulation of liquid or gas flow.
This valve is used for drilling, fracturing, mud circulation and surface high pressure gas injection manifold gas and other equipment. The valve also features the most significant is that, when it closed, the inlet and outlet pressure difference between, make two plates firmly pressed together, to achieve the function of sealing off. Especially the sudden rise in the face of pressure, or pressure due to leakage caused by the sudden drop in emergency incidents such as the case may be pre-set by high and low pressure sensor signal values, so that it automatically shut down and cut off. This can avoid a significant risk of accidents.
The outstanding merits of the valve also is compared with other types of throttle, which has the longest life, most erosion damage and wear ability.
Unique plate design
Orifice by a special molded tungsten carbide materials, from diamond grinding wheel by rotating the stem, adjust the orifice opening size.
Close the throttle to achieve a real
All the closed position is designed to seal with a 17 ° Overlap in order to ensure sealing, even if has been worn, with the pressure of the surge, due to the special plate design will not affect the seal quality.
Tungsten carbide wear-resistant lining
Wear-resistant surfacing in the bush, to increase its service life, wear-resistant lining of scalability, suitable for corrosion resistance to withstand the impact of the stream, especially in the negative pressure to the drilling operation.
Versatility
For land and sea operations, to remote control, but also manual operation.
