8 inch Triple Offset Butterfly Valve

Reliable flanged triple offset butterfly valve for sales with 8 inch (DN200) port size, nominal pressure PN16. The sealing material of the hard seal butterfly valve is properly selected, so that the sealing, corrosion resistance, high-temperature resistance and wear resistance are reliably guaranteed.

Features

• The triple eccentric butterfly valve has small opening torque, flexible and convenient, labor-saving and energy-saving.
• The three-dimensional braided core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable to achieve no leakage.
• Flange triple eccentric butterfly valve is resistant to high pressure, corrosion resistance, wear resistance, long service life, etc.

Application

Tips: How to install and maintain the triple eccentric butterfly valve?

• During the installation process, the triple eccentric butterfly valve disc must stop at the closed position.
• The opening position must be determined according to the rotation angle of the butterfly plate.
• For the butterfly valve with bypass valve, the bypass valve must be opened first and then opened.
• Install according to the manufacturer's installation procedure, and install the heavy-duty butterfly valve on a solid base.
• The butterfly plate of the triple eccentric butterfly valve is installed in the radial direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is 0°～90°. When the rotation reaches 90°, the valve is fully opened.
• If you need to use a butterfly valve as a flow control, the main thing is to choose the appropriate valve size and type. The structural principle of the butterfly valve is especially suitable for the manufacture of large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, natural gas, chemical industry, and water treatment, but also widely used in cooling water systems of thermal power plants.
• Commonly used butterfly valves include wafer butterfly valves and flanged butterfly valves. Wafer butterfly valves use stud bolts to connect the valve between two pipe flanges. The flanged butterfly valve has flanges on the valve, and the flanges at both ends of the valve are connected to the pipe flanges with bolts.
