QB2 DOUBLE PORT EXHAUST VALVE
This valve is suitable for use on pipelines with water as the working medium, serving as a device to expel gas from the pipeline, thereby enhancing the efficiency of water transportation equipment and protecting the pipeline from deformation and rupture. When the pipeline is under negative pressure, this product can automatically draw in air to prevent pipeline rupture. This valve has a large exhaust volume with a double-port exhaust. When there is a white belt inspection hole for maintenance, the inspection switch should be closed and the maintenance can be carried out online.
