Introduce
The pneumatic u-type butterfly valve adopts the mounted structure, reducing the connection bolt of the valve body itself under the condition of high pressure and large diameter, enhancing the reliability of the valve and overcoming the influence of system dead weight on the normal operation of the valve.
Range of application
Pneumatic u-type butterfly valve is widely used in coal chemical industry, petrochemical industry, rubber, paper, pharmaceutical pipeline as the medium of the diversion and confluent flow or flow switching device.
