The valve is mainly used in the pipeline system, in order to prevent overpressure or maintain the pipeline pipeline system, when the pumps are shut down can also reduce water hammer shock. Also can eliminate water hammer device for large scale water supply system, equipped with a self cleaning strainer inlet and valve control side system, through the use of fluid properties, the proportion of larger, suspended particles with larger diameter can not enter the control system to ensure that the upstream water supply pressure, the main valve to a set value of the system of circular SMOOTH OPERATOR, the valve the sensitive opening and closing, safe and reliable, steady operation, long service life.

Note: the installation diagram of elastic valve seat seal or valve optional, suggest ≥ DN350 butterfly valve. The H value for reference purposes only, to the real actual size as.
