DIN JIS SS CS Flange Vacuum Butterfly Valve with Handle

JIS DIN SS flange vacuum butterfly valve is used in the dust-containing cold air or hot air gas pipeline of ventilation, environmental protection engineering in chemical industry, building materials, power station, glass and other industries, as a device for regulating or cutting off the flow rate of gas medium.

Product Details

Vacuum butterfly valve is used in the dust-containing cold air or hot air gas pipeline of ventilation, environmental protection engineering in chemical industry, building materials, power station, glass and other industries, as a device for regulating or cutting off the flow rate of gas medium. 

The valve plate of the valve adopts a clamping structure to clamp the sealing ring of the valve plate for better sealing. The valve is opened and closed with a locking function.

Suitable working media are air and non-corrosive gases.

Characteristics

The valve can withstand positive pressure;

The valve stem does not move up and down;

The direction of the gas path is changed by the electromagnetic reversing valve, and the cylinder driving butterfly valve is controlled to perform the opening and closing motion.

Used to turn on or off the airflow in the vacuum line.

Suitable media are pure air and non-corrosive gases.

Optional feedback signal device and electric valve positioner.

The work is stable and reliable, can be installed in any direction, and the valve stem will not move.

The structure is simple and compact, small and light, easy to disassemble and repair, and can be installed at any position.

90 degree rotation, quick opening and closing, can be installed in multiple stations, independent of the flow direction of the medium.

The utility model has the advantages of compact structure, light weight, easy installation, small flow resistance, large circulation and light operation.
