Butt welding hard seal metal butterfly valve
Butt welding hard seal metal butterfly valve
This butterfly valve is suitable for opening and closing or regulating medium on pipelines with high temperature, high pressure, fire prevention and heat preservation.
Ventilation butterfly valve
The ventilation butterfly valve is made of the same material as the valve body to form a sealing ring. The applicable temperature depends on the material selection of the valve body, and the nominal pressure is ≤0.6MPa. It is generally suitable for ventilation and regulation of medium flow in industrial, metallurgical, and environmental protection pipelines.
Hard Seal Wafer Butterfly Valve
Hard Seal Wafer Butterfly Valve
Because the butterfly valve of this product is designed on the principle of three-dimensional eccentricity, the spatial trajectory of the sealing surface can be idealized, and there is no friction and interference between the sealing surfaces. In addition, the sealing material is properly selected, so that the sealing performance and corrosion resistance of the butterfly valve can be improved.
Hard seal flange butterfly valve

The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by only rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. Application range Metallurgy, light industry, electric power, gas, waterway and other fields.
