Pneumatic cut-off butterfly valve installation and maintenance Pneumatic cut-off butterfly valve, electric ball valve is a newly developed long-life energy-saving butterfly valve. The butterfly valve is designed with three-dimensional eccentricity principle. The flexible seal and the new processing technology compatible with hard and soft multi-level sealing make the butterfly valve sealed when it is in operation, achieving leak-proof gas-tightness and prolonging the service life of the valve. Pneumatic actuator using crank structure, with a large output torque, small size, stable performance * and so on. With the use of valve positioner or solenoid valve can be used to achieve proportional control or switch control, suitable for gas, solid particles and liquids and other media. Can be widely used in papermaking, petrochemical, chemical, metallurgy, electric power, environmental protection oil, light industry, building automation and other industrial automation control system. Pneumatic cut off the butterfly valve installation and maintenance: 1, the installation of butterfly valves, valve body should be noted that the flow of signs to prevent the wrong direction of circulation, affecting the use. 2, the butterfly valve should be confirmed before using the valve under the premise of the pipeline to break through washing, so as to avoid welding slag and other debris scratched sealing surface. 3, the butterfly valve are generally set by-pass pipeline, in the repair or replacement of the butterfly valve, bypass flow can be used as usual. 4, pneumatic butterfly valve can be mounted horizontally in the horizontal 180 °, do not flip down the pneumatic actuator. 5, locator or solenoid valve debugging see the instructions. 6, pneumatic actuator crank for the square head structure, used as a manual device to use, failure to remove the gas source pipe directly to the manual wrench to achieve manual operation. 7, if found stuffing box leakage during use, tighten the gland bolts can be solved.
