The main problem of butterfly pneumatic valve 3)

failure: sealing leakage of pneumatic valve, butterfly butterfly plate, seal with sundry. Pneumatic valve, butterfly butterfly plate, sealed closed position match is not straight. , exports are equipped with flange bolt stress or pressure. . Fault:

sealing leak, pneumatic butterfly valve plate and ring with sundry. , pneumatic butterfly valve plate and seal closed position right is wrong. , exports are equipped with all kinds of flange bolts or clamping force. , the direction of the failure, pressure test requirements. 。
eliminate, eliminates impurities and clean the pneumatic valve cavity. , adjust the worm gear drive restrictions, such as screws or electric actuators. In order to realize the pneumatic valve closed position is correct. , Charles is equipped with flat flange and bolt clamping force should be uniform compression, and the direction of rotation arrow fault:

surface leakage current through a pneumatic valve, both sides of the gasket is broken, the flange or compressed clamping force of inequality.
eliminate:, replace the gasket. , the compression flange bolts ( Even forced) 。 This site keywords: pneumatic ball valve pneumatic ball valve pneumatic pneumatic valve pneumatic pneumatic valve pneumatic butterfly valve pneumatic butterfly valve pneumatic actuator pneumatic execution
