TD341W Flanged ventilated butterfly valve

Product introduction

The ventilating butterfly valve is processed into a sealing ring with the same material as the valve body, and its applicable temperature is determined with the selection of the valve body, nominal pressure ≤1.0MPa, generally suitable for industrial, metallurgical, environmental protection and other pipes for ventilation regulating medium flow.

Standard specification

Design and manufacturing standard: GB/T 12238-1989; JB/T8692-1998 Structure length standard: GB/T 12221-2005 Connection flange standard: GB/T 9115.1 Pressure temperature grade: GB/T 12224-2005 Test and inspection standard: GB/T 13927-2008

Structural characteristics

Ventilation butterfly valve design novel, reasonable, unique structure, light weight, quick opening and closing.
The butterfly valve has the advantages of small operating torque, convenient operation, labor-saving and dexterous. The use of adaptable materials to meet the low, medium and high temperature of different media and corrosive media. No connecting rod, bolt, etc., reliable work, long service life, not affected by the flow of the medium

Application range

Ventilation butterfly valve applicable temperature with the valve body selection, nominal pressure ≤1.0MPa, generally suitable for industrial, metallurgy, environmental protection, chemical, building materials, power stations, glass and other industries in the ventilation, environmental protection engineering dust containing cold air or hot air gas pipeline, as a gas medium to adjust the flow or cut off the pipeline control device. The ventilation butterfly valve should generally be installed horizontally in the pipeline.
