Ventilation butterfly j Price

Ventilation valve ventilation butterfly valve processing and use of the same material as seals, their body temperature with suitable selection may be, nominal ≤0.6MPa, applied containing chemicals, building materials, power plants, glass and other industries ventilation, environmental engineering Dust cold or hot gas duct, adjusting the flow rate or as a gaseous medium pipe cutting control means. This type valve in the pipe should generally be installed horizontally. Ventilation butterfly valve is a circular disc for opening and closing member and with the stem rotation to open, close and adjust a filter accessories valve fluid channel. Butterfly not only simple in structure, small size, light weight, material consumption province, small installation size, and the driving torque is small, simple, rapid, and also at the same time has a good flow regulation and closed sealing characteristics, in medium and large caliber, the the use of low-pressure areas, butterfly valves is the dominant form. Ventilation valve has a simple structure, small size, light weight, material consumption province, small installation size, switch quickly, 90 ° reciprocating rotary drive torque characteristics of small, used to cut, turn, adjust the line of medium, having good fluid control features and closed sealing performance.
