Pneumatic cut-off butterfly valve installation and maintenance of pneumatic cut-off butterfly valves, electric ball valve is the new development of long-life energy-saving butterfly valve. Three-dimensional design of principle of eccentric butterfly valve USES the elastic sealing and multi-level seal compatible with the new technology of processing of hard and soft, so that the butterfly valve seal when he worked in running *, can achieve without leaking gas seal and adopt eccentric design extend valve life. Pneumatic actuators used crank arm structure, with output torque, small volume, stable performance can be *, etc. With the valve positioner or electromagnetic 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-off valve installation and maintenance: 1, installing a butterfly valve, should pay attention to the body to sign, in order to avoid flow direction error, affect the use. 2, under the premise of butterfly valve before use should confirm that the valve is fully open to break the wash pipe, in order to avoid has the sundries such as welding slag scratch sealing surface. 3, butterfly Industrial Valves is generally set the by-pass pipe, the repair or replacement butterfly valve, can use by-pass pipe using process as usual. 4, pneumatic butterfly valve can be installed in vertical lie within the range level 180 °, never will flip pneumatic actuators downwards. 5, the locator or electromagnetic valve please refer to the manual for debugging. 6, pneumatic actuators crank arm to the lag structure, used for manual device, fault when removing the air supply pipe directly using hand wrench manual operation can be realized. 7, in use process of gland leakage is found, tighten a press cover bolts can be solved.
