Pneumatic regulating butterfly valve installation and maintenance

pneumatic regulating butterfly valve is the new development of long-life energy-saving control pneumatic valve. Design of principle of pneumatic valve adopts three-dimensional eccentric butterfly elastic sealing and multi-level seal compatible with the new technology of processing of hard and soft, make the butterfly pneumatic valve when running work reliable sealing, can achieve without leaking gas seal and lengthen the service life of pneumatic valve adopts eccentric design. Pneumatic actuators used crank arm structure, with output torque, small volume, stable and reliable performance, etc. With the pneumatic valve positioner or solenoid pneumatic valve used proportional control can be realized or switch control, is suitable for the gas, solid particles and liquid medium. Can be widely used in papermaking, petrochemical, chemical, metallurgical, power, environmental protection, petroleum, light industry, building automation and other industrial departments of automation control system.
pneumatic regulating butterfly valve installation and maintenance:
and installing a butterfly pneumatic valve, pneumatic valve should be paid attention to the flow on the logo, in order to avoid flow direction error, affect the use.

, pneumatic butterfly valve should be confirmed before use pneumatic valve fully open under the premise of through the pipe to wash, in order to avoid has the sundries such as welding slag scratch sealing surface.

, pneumatic butterfly valve is generally set the by-pass line, in the repair or replacement butterfly pneumatic valve, can use by-pass pipe using process as usual.

, pneumatic butterfly valve can be installed in vertical lie within the range level °, never will flip pneumatic actuators downwards.

, electromagnetic pneumatic valve locator or please refer to the manual for debugging.

crank arm to the lag structure, pneumatic actuators, used for manual device, fault when removing the air supply pipe directly using hand wrench manual operation can be realized.

, in use process of gland leakage is found, tighten a press cover bolts can be solved.
