Overview of clamp type turbine butterfly valve:
The clamp type turbine butterfly valve is a disc butterfly plate that rotates around its own axis inside the valve body to achieve opening and closing or adjustment. The butterfly valve is usually 90 ° from fully open to fully closed. Quick opening and closing, low fluid resistance, and can be operated frequently. Simple structure, small size, and light weight. It can transport mud in pipelines with small liquid accumulation. The adjustment performance can be sensitively adjusted from 0 to 90 °.
Main technical parameters:
Working temperature: X: 60 ℃ J: 80 ℃ XB or JB: 150 ℃ XC, JC, F46:200 ℃ SDJD: 250 ℃ XE, JE: 250 ℃
Valve body materials: cast iron, carbon steel, stainless steel
Valve stem material: 35 # stainless steel
Applicable media: water, steam, oil, and corrosiveness.
Features:
This clamp type turbine butterfly valve adopts a double eccentric structure, which has a tighter sealing function and stable sealing performance. The sealing pair is made of stainless steel and nitrile oil resistant rubber, which have a long service life. The rubber sealing ring can be located on both the valve body and the butterfly plate, and can be suitable for different characteristics of media for users to choose from. The butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance. The overall paint baking can effectively prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced. This valve has a bidirectional sealing function, and is not controlled by the flow direction of the medium or affected by spatial position during installation. It can be installed in any direction. This valve has a reasonable structure, flexible operation, labor-saving, and convenient.
