Automatic wafer butterfly valve is a common industrial valve, it is driven by the actuator, to achieve the control of the fluid medium, especially suitable for the medium is viscous, containing particles, fibre nature of the occasion; widely used in food, environmental protection, light industry, petroleum, chemical industry, teaching equipment, papermaking, electric power, and other industries in the automatic control system of the industrial process.
Features of automatic wafer butterfly valve:
1, strong function: intelligent, regulating, switching.
2,Compact size: the volume is only equivalent to about 35% of similar products.
3,Protection devices have double limit, overheating protection, overload protection. Full travel time 15 seconds, 30 seconds, 45 seconds, 60 seconds and with manual function.
4,Intelligent numerical control: the built-in module adopts advanced computer monolithic and intelligent control software to directly receive standard signals output from computers or industrial instruments, etc. to achieve intelligent control and precise positioning of the valve opening.
The automatic wafer butterfly valve before the installation of the requirements of the instructions:
1, installation before the start of operation, with the air spray wash to remove the piping on the external objects, piping the inner surface with water to clean up.
2,Check carefully whether the use of the valve is consistent with its performance specifications (temperature, pressure).
3,Check the valve channel and sealing surface whether there are debris, and timely removal.
4, the valve should be installed in a timely manner after unpacking, do not loosen any fastening screws or nuts on the valve.
5,Clamped butterfly valve must use special butterfly valve flange.
6, electric butterfly valve can be installed in any angle of the pipeline, in order to maintain the convenience of the recommendation is not inverted installation.
7, butterfly valve flange in the installation must ensure that the flange surface and sealing rubber centred, screws evenly tightened, the sealing surface must fit intact; if there is a screw tightening strength is not uniform there will be a rubber bump stuck butterfly plate, or the top of the butterfly plate caused by the leakage of the valve stem at the valve stem.
