Air ventilated flanged butterfly valve-Pneumatic valve series-气动阀厂家-上海冠环阀门制造有限公司

Product overview

Pneumatic ventilation flanged butterfly valve is a valve designed for ventilation systems in various industries, mainly composed of pneumatic actuators and ventilation butterfly valves. The material selection of the ventilated butterfly valve is determined according to the high temperature and normal temperature used in the field. The valve is mainly suitable for metallurgy, environmental protection, chemical, power station, glass and other industries in the ventilation system pipeline. Using compressed air as the power to accept industrial signal instructions, drive the valve stem to drive the rotation of the disc to complete the valve switching and adjustment.

Product characteristics

1, the design is novel and reasonable, the structure is unique, the operating torque is small. And easy to operate, smart switch open and close quickly.

2, according to the on-site pressure and temperature to choose the valve material to full room temperature, high temperature different temperature conditions, etc.
