Pneumatic cut butterfly valve installation and maintenance

pneumatic cut-off butterfly pneumatic valve installation and maintenance of pneumatic cut-off butterfly pneumatic valves, electric ball 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 seal can be *, can achieve without leaking gas seal and adopt eccentric design could prolong the service life of pneumatic valve. Pneumatic actuators used crank arm structure, with output torque, small volume, stable performance can be *, 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 cut butterfly valve installation and maintenance, and installing a butterfly pneumatic valve, the flow of air should be paid attention to the body mark, 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 valve, butterfly is generally set the by-pass line, in the repair or replacement pneumatic valve, butterfly 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 with a manual wrench manual operation can be realized. , in use process such as the discovery of gland leakage, tighten a press cover bolts can be solved.
